I don't know, musicals, classical music, pink floyd, trad jazz, singer songwriters, folk music all seem pretty unrelated. I'm sure I could think of others, but I don't really listen to any of those, apart from a few pink floyd tracks now and again.
Anything other than dnb i guess, there was a thread like this in waffle though i think.
On topic though listen to alot of ambient, which i suppose is as far as you can get from drum & bass.
Rock wise listen to Pink Floyd, Tool, Metallica etc. Darkside are fast becoming my new fave band, their Boiler Room set is awesome, well worth checking out
Huge fan of Wolfgang gartner, overwerk and a few other non-conformist electro-house guys. But when it comes to actoustic stuff ive pretty much never listen too, except maybe jazz when it pops up. Fucking love jazz.
