I was watching YouTube normally, and I found a very interesting game called "Beat Hazard", It looks like some kind of Asteroids but cooler.

Yeah, it and the sequel(s) are pretty fun for what they are. It generates gameplay that is somewhat based on the music that is playing, which can be your MP3 collection (might work with streaming, never tried). If procedurally generated bullet hell sounds good, it's enjoyable in short bursts.
