Well, this is a rather interesting thread...
Here at work I cannot access the entire Web because of security retstrictions, so I rely on rotating my own CDs on my hdd. (Yeah, I know. Security is so tight I cannot listen to music, but I can logon to the forum and download my own CDs onto the machine...I didn't say it made sense!
)
At the moment, I have a rather eclectic selection. Everything from Bjork to The Who and The Sex Pistols and the SpongeBob Squarepants soundtrack (thanks to my kids). I like "Bikini Bottom" off that album.
Otherwise, depending on what I am doing and how I feel, I listen to various noise.
When I am in deep concentration mode, I like to listen to a collection of CDs from the Sacramento Choral Society. 100 voices accompanied with instrumentation--all in Latin. It has an amazing effect on my consciousness for some reason. My favorite is "introitus-in te, domine, speravi". Something about that piece drives my consciousness into a focus that drives thought and coding. I think it helps because I can simply enjoy the music without being distracted by lyrics because I do not know any Latin.
Otherwise, I listen to rock. Not heavy metal...The Police, Pink Floyd, Madness, ELO, Devo, The Clash, The Cars, etc.
I guess this kind of dates me as well.
