I could almost make an alphabet with the genres I know and love! Might as well, since I have multiple tiers of how much I like them, I'll list them here:
Tier 1: "Huh. Its pretty good."
Baroque, Classical, Drumstep, Electro Swing, Future Bass, Future Funk, Glitch Hop, Hardcore, Synthwave, Synthpop, Vaporwave, ...
Tier 2: "Now that's pretty cool."
Bossa Nova, Chillwave, Complextro, Drone, Extratone, Electrance, Glitch, Hi-Tech, Jazz, J-pop, J-core, K-pop, Kawaii Bass, Melodic Dubstep, Nu-Trance, Orientalstep, Progressive Trance, Psytrance, Speedcore, Splittercore, Trance, Techno, ...
Tier 3: "I'm into this!"
Artcore, Ambient, Breakcore, Chillout, Chillstep, Chiptune, IDM, Lowercase, Lo-fi Hiphop, Lo-fi Jazzhop, Psybient, ...
(Note: I like a lot of genres but its hard to name them all, so I'll edit this occasionally)
