2000 -2012: I have Sigur Rós, some rock and Four Tet electronica, and 2012 dubstep from Dubstep.NET.

anything from 1950's to 2010 although very little from the 21st century,

For me, it's about 1965-1980's rock music, such as Zeppelin, Ozzy, Beatles, Pink Floyd, Jethro Tull and Alice Cooper. The only songs I like from post-90's are from bands that started before then, or the newly formed Sheepdogs.
