Yesterday when me and a few friends were at the gym spinnin, a song came on that we all seemed to dig. It was a melodic trancer with a marimba or xylophone kind of instrument playing a melody from the very beginning for about 40 secs or so, then getting into a really nice groove. Then the marimba/xylophone/whatever-it-was comes back in and practically goes thru the whole track. The melody has a classical approach to it, and I know I've heard it before. My first though was some mix of Woody - Unfinished Symphony, but I dont have it around to make sure wether its that one or not.

Anyone knows what it could be?

Edit:
Went to an online store to check out Unfinished Symphony, and its not that one. The melody has the same kind of classical transitions though, only a bit more minimalistic due to the choice of main instrument.
