Holiday music
I like a lot of different genres, so it's hard to pick a favourite as my tastes aren't really the most consistent.
You can put my music playlist on shuffle and it will probably go from classical to screamo to Jpop to a random sountrack to something that doesn't even sound like proper music.
Though I tend to like anything that's derived from the punk genre. Alternative rock, new wave, post-punk, post hardcore, etc etc. I suppose Visual Kei would fall under this umbrella as well.
I don't know if it's really my favourite, but it's what I like the most consistently.
