I'd say certain Alternative rock and Indie. Since it's such a huge genre, it's kind of hard to explain the exact sound that my brain finds so appealing, but I tend to like the softer side of the Alt&Indie, almost leaning towards the despair sound sought after by Radiohead and the likes. My perfect music is honestly a diverse song, the ones I tend to like have aspects of so many distinctly different genres. I like it to be, as I said, Indie or Alt, lately with some folk thrown in there and some warm (albeit subtle) electronic in there, not overbearingly so but enough to really add to the song as a whole.
Lately I've been digging Half Moon Run's album Dark Eyes, and looking back this kind of embodies what I said. Also, certain areas of punkpop have always struck me right, but only very certain bands. Most punkpop is just... Not my style to say the least haha.
