My collection is available as YT playlists.

Music (albums), contains mostly (you guessed it) albums and games OST and stuff of that sort. Doesn't contain the mixes I listen to though, I just search those every time I want to listen to one, like "drumstep mix".

Music (tracks) contains random songs from artists I like or if I like only one song from an artist or something like that. I also use it to not forget songs that I sometimes want to listen to but often forget the name of.

Anime songs I just use to put in anime ops/outros I like. Don't often put in something other than an op/outro.

And Game Grumps remixes just contains the GG remixes I like. There's some good stuff in there though a lot are good because you remember the moment that the remix is remixing.
