it's free for anyone who's interested in Internet Radio (basically Satellite Radio)
Go to the Itunes Radio,
click on "Electronica"
click on "DI.fm Vocal Trance ~ "a fusion of trance, dance and chilling vocals"
it's really incredible. very laid back, very cool.
Aside from some strong ass coffee it's the only thing keeping me awake while I cram for tomorrow morning's Spanish exam.
