I gave every train in New York an instrument

Each line in that view represents a subway line's route. Each note/dot along each of those lines is a train that is currently at that stage of progression through the route (based on geo location from the MTA).

They assigned a different instrument to each subway line.

If you turn on the map portion of the UI, you can see where the stations are. This is why there’s a dearth of notes over the east river (no stations on the water), other than the one stop at Roosevelt Island, for the F or the M, depending on the time of day.

AI generated music isn't out there as some experiment by some artists, trying to make sense of something, make a statement, or just for the sheer enjoyment of creating something. It's there because of money. I know, there are exceptions, and I'm fine with those.

The AI music I'm against is the type that's made by the likes of Spotify, because they don't want to pay artists. It's music that only exists because Spotify would like to make more money. That motivation, to me, corrupts the product. AI music isn't created for the sake of creating music, it's created as a means towards a goal, money. I don't think that the management at Spotify particularly cares about music, it's just a means on the path to money. If they could be more profitable selling something else they would.

You can argue that a lot of bands solely exists because a record labels wanted to create a profit generating device, or that some artists are artificially created and wouldn't survive without auto-tune and a media machine pushing their music. I think that's bad as well, but often many of these artists do have some level of talent and actually do care about music.
