My absolute faves are: Arctic Monkeys, Blur, Pixies, Bloc Party, The Killers, White Stripes, The Raconteurs, The Hives, The Strokes and many many more.
from older stuff: Jimmy Hendrix, The Beatles, The Doors and Rolling Stones.
and in fact I don't listen to k-pop at all - well, maybe when I'm watching a drama and the ost is good I'll listen to it a few times, but besides that my knowledge about k-pop ends on Big Bang. Still waiting for a day (or better a song/artist) that'll make me as addicted to k-pop as I am to dramas.
