- The rave music sounds great. But that's because EDM can be quite out there in terms of musical construction.

- The guitar sounds weird because it doesn't sound like chords a human hand can make on a tuning nobody tunes their guitar to - with a strange mix of open and closed strings that don't make sense. I think the restrictions of what a guitar can do aren't well understood by the model.

- The disco chord progression is bizarre. It doesn't sound bad, but it's unlikely to be something somebody working in the genre would choose.

- meditation music - I mean, most of that genre may as well just be some randomized process

- drum solo - there's some weird issues in some of the drum sounds, things like cymbals, rides and hats changing tone in the middle of a note, some of the toms sound weird, it sounds like a mix of stick and brush and stick and stick and brush all at the same time...it's sort of the same problem the solo guitar has where it's just not produced within the constraints of what a drum player can actually do on an instrument made of actual drums

- sound effects, all are pretty good, a little chunky and low bit-rate or low sample-rate sounding, there's probably something going on in the network that's reducing the rate before it gets build back up. There's a constant sort of reverb in all of the examples

I honestly can't say I prefer their model over some of the musicgen output even if their model is doing a better job at following the prompts in some cases.

All of the models have a very low bitrate encoding problems and other weird anomalous things. Some of it reminds me of the output from older mp3 encoders, where hihats and such would get very "swishy" sounding. You can hear some of it in the autoencoder reconstructions, especially the trumpet and the last example.

However, in any case, I'm actually glad in some ways to see the progress being made in this area. It's really impressive. This was complete science fiction only a very few years ago.
