Yo bud, I only listen to trance during a game of chess. I find it very rhythmic to soothe me while I play, and that it's helped my concentration as I beebop with my moves for where and where not's..

This is what I'm currently listening to.

I have as well many blogs of trance than just this. =]

The Sirens of the Sea album is pretty good already, anything Anjuna is good (and naturally also Armin) :)

Anjunabeats 7 is a fantastic album (as are all the A+B compilations), in particular my favourite tracks on it are Aurora and Everywhere You Are, I'd have a look for them on YouTube.
