I really feel like there are too many genres on Spotify to the point where it literally doesn't even matter anymore. You just pick a word and shove a couple of songs, regardless of association and it's a new genre.
'Otacore' used to mean generally anime songs, then grew to meaning broaderly fandom related songs. Okay, that's a decent enough 'new' genre... So why did 'DreamSMP' get a whole new genre?? Those songs surely should just go into Otacore. Especially since a lot of songs in ''DreamSMP'' are just songs where people who don't involve themself in that fandom listen to. I know Undertale is classed as DreamSMP music, and I've heard mixed reports that Lemon Demon is too for some reason.
I listen to Undertale music because I like undertale. I hear that it's used in one of those people's streams, so it was classed under a new genre? Why does that specific sub-culture get a new name?
I dunno. I really feel like in recent years with the addition of all of these really niche and specific genres it really loses the point and spreads everything far too thin. Perhaps I am just bitter I got DreamSMP in my top five without at all being a fan of DreamSMP haha.
