Mine is here: http://www.last.fm/user/zzffnn
I actually do not use last.fm at all, but I did it to see if I can find someone with a highly similar music taste. It is difficult for me to pick 8 of my favorite artists to represent my music taste at last.fm. I listen to lots of genres; I have about 2.5TB of music from the genres of New Age, Vocal, Instrumental/Acoustics, World music, Downtempo, Bluegrass, Rock, Jazz and Classical.
As for internet radio, I use MOG.com to listen to music that I do NOT own.
