Hey man, Mpspace compresses the file to make it of a smaller size, same name but different process. While myspace does make everything sound like crap and I encourage everyone to use Soundclick (sounds sooo much better:)). The pumping is definitly in his Compression technique. I am aware of the differences between data compression and dynamics compression. TBH I did not go his Myspace to listen to his tunes but I know from my own experience that MySpace does "something" to the music. I suspected they boost highs and lows and compress dynamics but I don't know for sure.
