sounds pretty well balanced.
nothing like a train song.....
sounds good to me.
One of the hardest things with BG music is to get the instruments captured properly. IMHO the hardest one to get sounding right is the bass. 90% of the time it is an old upright acoustic with a mic on it...... on the speakers I'm listening on there is a bit to a boominess to the bass. I'd try rolling the lower end off a bit with EQ to clean that up.
the rest sounded pretty decent.
