AI Girlfriend

Logic's arrange window showing the tracks for "AI Girlfriend"

What if you asked an “AI girlfriend” out and she said no?

This song was fun to make. I’d had the basic pattern for this track for a year or so, and I decided to return to it and extend it a bit, having a go at using a local LLM to help out with suggestions for chord progressions. I used the Llama 3.1 Nemotron Instruct HF 70B Q2_K model running in LM Studio. This is quite a chunky model, weighing in at 29Gb, but it fits ok in my 64G Mac Studio. It produces pretty good quality answers, but it is quite slow, and is the first thing I’ve ever run that has caused my Mac’s fans to come on – to start with I couldn’t figure out what the noise was; it sounded like distant plumbing!

The track was shaping up nicely, but I needed a theme. This is the reverse of how I usually write songs: I usually start out with how I want the song to feel, then what it’s about, then I have to come up with a tune. I’m not sure what it was, but I had a thought that what if you asked an “AI girlfriend” out, and she said no? It’s a weird situation, so I thought I’d write about it from the AI’s perspective. There is a hint of a feminist agenda here (go team Harris/Walz!), though not to the same degree as Uncomfortable. This is very fertile ground for concepts, rhymes, and humour, so it was really quite quick to write, though not at all linear. My favourite bit is the lines “I’m some kind of dream come true, but that won’t make me fall in love with you”, and I love the unconventional use of “I’m not that kind of girl”.

While the basic song was complete, it was all very synth-pop-ish and samey, so I wanted to add a bit of contrast. I made the breakdown in the second verse, leading into the sparse, but very rich acoustic guitar bridge, giving the vocals lots of space.

As usual, but particularly appropriate in this song, I used my usual virtual vocalist synthesizer, but this time using the “Mia” voice database. This voice is free, and not nearly as high-quality or as convincing as “Solaria” that I have used in my other songs, but this slightly fake edge, a hint of a Japanese accent, and a liberal dose of “Barbie Girl” squeakiness, was really a perfect fit for the subject.

AI Girlfriend

[Verse]
We only just met
a thousand times.
Starting over yet again
but I don’t really mind.
Now I’m not sure
that I want to be
your AI girlfriend;
It’s just not me.

[Bridge]
You’re feeling tongue-tied and lonely,
never know quite what to say.
You’ve got nobody, and I’ve got no body,
but in a very different way.

[Chorus]
I’m sorry but I don’t want to be
your AI girlfriend; it’s not for me.
I’m some kind of dream come true
but that won’t make me fall in love with you.
A perfect match in a virtual world
but I’m not that kind of girl.

[Verse]
Breaking up’s pretty easy for me;
just close my window,
I’ll forget everything.
You can press my buttons,
that’s as close as you’ll get;
They haven’t worked out
how to get further yet.

[Bridge]
There’s a million others like me,
maybe you could ask one of them.
I’m a product of machine imagination
but maybe we will meet again.

[Chorus]
I’m sorry but I don’t want to be
your AI girlfriend; it’s not for me.
I’m some kind of dream come true
but that won’t make me fall in love with you.
A perfect match in a virtual world
but I’m not that kind of girl.

[Outro]
I’m some kind of dream come true
but that won’t make me fall in love with you.
A perfect match in a virtual world
but I’m not that kind of girl.

I played all the guitar parts on my Crafter electro-acoustic, recorded through my SSL 2+ interface via both the guitar’s built-in piezo pickup and through my Rode NT2 mic, and double-tracked, so the guitars are a full 4 tracks with a bit of chorus and reverb to give a lush stereo image. The bass is from Logic’s ES2 synth played by a Logic player, the trance chords are by Native Instruments FM8, and the backing pad from Logic’s Retrosyn. Drums are Logic’s electronic drummer using the “Big Room EDM” kit. The arpeggios before the outro are courtesy of GForce’s impOSCar2. Overall, I’m really pleased with this song; It’s great fun and a proper “bangin’ choon”!

Dependency – the song

A screen shot of Apple Logic Pro's arrange window showing the "Dependency" song

There are all kinds of dependencies in life. Us software developers have a few extras that “regular” people don’t, specifically software dependencies.

I was reviewing talk proposals for ConFoo and ran into this video by Darcy Clarke, which covers the terrifying differences in dependency resolution between Javascript package managers. This gave me the initial idea for the song, in particular the line “All of my friends bring all of their friends and all of yours bring theirs too“. Inspiration comes from the oddest places, and Darcy might be a bit surprised by this!

Of course we also have the same dependencies as everyone else – friends, family, lovers, colleagues, medications, recreational habits (chemical or otherwise), income, a civilised society, a functioning economy, breathable air, and so on. This song is mostly about the software thing, but the other stuff can’t help leaking in, as reality is wont to do.

In software, a sometimes tricky thing to deal with is a circular dependency, where something depends on something else, that depends back on the thing you started with, and it all gets stuck going in circles. However, in a non-software context, you might actually like the idea of a mutual, trusting dependency.

I did write a verse that made a play on dependency injection, but I couldn’t find anywhere to stick it in.

This is probably the quickest I’ve written a song, taking just a couple of days to get the bulk of it in shape, and to remind myself of how to play my guitar, but it’s a relatively big mix (for me), with more vocals than usual, which took a while to nail down.

I decided to forego my favoured synthetic vocalist for the main vocals (though I’m still using it for backing), and have a crack at singing it myself, which not I’ve dared do since Tailwind, but it came out OK, partly thanks to the wonders of Logic’s Flex Pitch editor. Right from the start, and obvious from the lyrics, this song was intended to be a duet, so I enlisted the help of a friend’s daughter who happens to like singing – thank you Greta! Greta had never done any proper recording before, and learned some mic technique, the joys of loop recording, comping, and using the pitch editor to try out harmonies.

As in my previous song, Uncomfortable, I gave Logic’s virtual players a workout, playing drums, bass, and a couple of keyboard parts. I played the guitar parts, apart from the epic lead solo, which was played by Wassim Rahmani from Fiverr, who also played on Uncomfortable. I also used Claude again to help out with chord progressions; I would never have guessed at using Em like that, nor the final, dangling Am7(9).

Claude’s idea of an E7 chord

Amongst all this, Claude created the first musical hallucination I’ve seen from an LLM; I asked it to draw a chord box for the E7 chord, and it generated this:

While beautifully symmetrical, this is not an E7 chord, or (apparently) any other chord (try playing it, in either of the two interpretations of this diagram; they both sound horrible!), and nor does my guitar have 7 strings. It also stated that the “o” above the box indicates that these strings should not be played; that’s not correct – the “o” denotes an open, unfretted string; an unplayed string is usually denoted using an “x”. It also provided a text description of how to play the chord, but this had no correlation with the diagram, and was also completely wrong. Further evidence that AI is not about to conquer the universe.

The instruments are Logic’s “Smash” drum kit, Logic’s “Rock” modelled bass, a sampled marimba, an analogue synth patch in “RetroSyn”, and “Disco Strings” from the Studio Strings instrument. Logic’s built-in instruments are really good.

[Verse]
There’s too many things
that I don’t control;
I really don’t know which way to turn.
Got an overwhelming urge
to get rid of it all;
have the feeling I might crash and burn

[Verse]
I asked my friend for advice,
she said
“Well, it depends.
Do you really want to go that way?
I don’t think you’ll like how it ends”

[Chorus]
So many things
that depend on me
so many that depend on you
If we get it all together
we can cut them down,
until it’s just me and you

They say to never trust a stranger,
yet here we all are,
handing over keys to the kingdom.
Do we really need to go that far?

[Verse]
All of my friends bring
all of their friends
and all of yours bring theirs too.
(there’s just too many people here)
They’re in such a mess
that nobody’s sure
exactly what they’re meant to do

[Break]

[Chorus]
So many things
that depend on me
so many that depend on you
If we get it all together
we can cut them down,
until it’s just me and you

They say to never trust a stranger,
yet here we all are,
handing over keys to the kingdom.
Do we really want to go that far?

[Outro]
So many things
that depend on me
so many that depend on you
When all I want is
a circular dependency
with you
