I find it harder and harder to stick some bands in certain genres, so I'll just throw some bands out there: Oasis, Sex Pistols, The Hives, Godflesh, Tori Amos, Loreena McKennitt, Public Enemy, Entombed, Primal Scream, Sickboy, Atari Teenage Riot, Air, Jesu, J.S. Bach, Richard Wagner, Kenji Kawai, Wu-Tang Clan, The Damned, Iron Maiden, Tommy february6, Perfume, Megadeth, In Mourning, Kate Bush, just to name a few (heh).
Nevertheless, I tend to listen to more guitar based bands, especially the extremely heavy, loud, fast kind (see, Earache Records). I blame this on having older brothers, all of whom were metalheads.
