i've long stated my Main Genre of karaoke songs is songs about heartbreak (mostly "breakup songs" but I need to cover longing also, so iori minase's futari no kioku, kanata amane's bessekai, jin's additional memory, utada hikaru's one last kiss), but I'm starting to realize my second Main Genre is any song that is sufficiently sassy (himehina stuff, dangerous marine smell, ikenai borderline, etc)
my third genre of course is 'anison from 2007'
