I'm into bands like Bush, Beck, Catherine Wheel when it comes to alternate stuff:
I also like Rammstein, Metallica, Iron Maiden, and Marilyn Manson's rock/metal songs.
I'm also into the 'lighter' forms of rock like Smashing Pumpkins (1979, Today, Bullet with Butterfly Wings) and Green Day (Holiday, Troubled Times, Boulevard).
There's also this small 90's indie band called Weezer I used to listen to growing up.

I like classical shit too. Stuff like the 2001: A Space Odyssey soundtrack and Beethoven's Moonlight Sonata (the slower version) really get me into the 'zone' when I'm writing an RP doc. Also, whoever created the piano version of Yann Tiersen's Sur Le Fil and Summer 78 is a genuis.
