A 6 month journey into classical music

All my life I basically liked classical music, but it was a very casual thing.. clicking on the occasional Chopin or Mozart piece on Youtube, listening to the opera radio stations in GTA games, stuff like that. Sometime late last summer I stumbled upon the Goldberg Variations and became obsessed with them; gradually a fascination with the whole tradition developed. It has been a very pleasant addition to my life and I'm already grateful to it for helping me through a rough patch.

These are the composers I've explored to a position where I'm more or less comfortable judging where I stand in relation to their output right now, and the tiers are how often I get the urge to listen to their music. I'm kinda musically illiterate so it's hard for me to explain why I like what I like but I think I'm attracted to the more melodic pieces out there. I can list down the pieces I like from specific composers if anyone is curious.

I'd love to get some recommendations on composers to explore next!
