Up til now, I've been convinced (foolishly, maybe) that there was something special about music that AI just wasn't going to be able to do well. Now, I'm not so sure.
I think modern popular hip hop is probably an easy target - the music itself is relatively simple, and especially for an absolute chart-destroying monster like Drake, there's a huge amount of singing / rapping / voice to use as training data.
I'm somewhat more skeptical on genres that involve complex instrumental playing and more dynamic vocal performances, but I think this track sounding so convincing is evidence that we're making big strides.
On the other hand, there's something about music that I truly don't think AI can touch, and that's this sort of undefined "cool" factor. I'm a rock / metal guy, and there's something just awesome to me about a group of guys up on stage rocking out, but the cool factor is definitely a big part of hip hop too.
Last thought - I'm not sure if this song is as good as I think it is, because I don't really listen to Drake. I recently ran across an AI generated Nirvana song, which was also pretty well done - but it was still just on the edge of the uncanny valley for me. Maybe big Drake fans would feel the same way about this, idk.
