I installed this software and looked at a couple of flac files during my lunch break. Pretty neat stuff.

I looked at some Bock and Chopin (classical and piano) and it was very clean.

I looked at dave matthews band "stand up" album. It looked pretty good. Not quite as good as the classical songs but still very good.

I looked at an mp3 I donwloaded from a local club DJ and WOW. There was no background color at all.. just a huge blob of blue allthe way across. (It made santana look great!)
