I'll write a comment after I've listened to it...
3 and 1/2 hours is pretty insane, for being a mix.
Edit : I listened an hour or so, I accidently pressed V instead of C in Winamp.
I'll listen to the other half tomorrow :b
I've recently got one of classmates into psy-trance (he makes trance music). I suggested him Infected Mushroom at first then a few other songs from other artists.
He seems to like it/them.
