Digitally Imported Radio (www.di.fm) has been around for a decade. I've enjoyed their music from the days of SoundJam and early iTunes and Web streaming. Now their channels are built-in to Sonos and other places, but no matter the place you get your music, their channels are excellent.
My preferences include their Trance, Classic Trance, Goa-Psy Trance, Hard Trance and Vocal Trance channels. Now they've got an Android app. I just sent the app to all my devices. Go get it. :)
