vocaloid stuff and moe breakcore whatever its called mostly. sometimes happy hardcore/j-speedcore (whatever you call the genre the hardcore tano*c members do), bubblegum dance/eurobeat (specifically stuff thats either in bemani games or otherwise made by producers who do stuff for those games) and j-rock as well
I listen to a variety of genres in general, but my playlist is mostly filled with rock and indie. By the way, I can recommend a great band called Good Kid, their music has a pretty geeky vibe, and they even have 8-bit versions of some of their tracks, which is super fun.
I listen to a mix of everything, really — mostly alt rock, a bit of synthwave, and some lo-fi when I need to focus. Depends on the mood, but I’m always up for discovering something new!
Right now I’ve got "And Your Bird Can Sing" on repeat — such an underrated gem. The guitar work on that track is insanely tight, and it always puts me in a good mood. Classic Beatles energy!
