Inspired by this post on Binomial-theorem's blog, I am going to make a collection of the music that I like, consisting mostly of artists. I'll try to put down at least one notable song from each artist on the list. There will also be a few random songs that I like just for their distinctive melodies or something.

There's a lot of edm in the second list (of songs). That's cuz I like a lot of edm, but it's not artist-specific. I listen to a lot of edm but I don't search or listen exclusively to any artist. Hopefully when I look back at this list and compile a new one, I'll have found a few edm artists I really like.

*As I remember more songs/artists I like, I'll edit.
