Obviously it is best to purchase directly from the band, but in general (and specifically for Watershed), which point of purchase is most profitable for the band: itunes or a retailer?
As someone who gets no time to get to CD stores and having iTunes conveniently placed in front of him, I resent that.
I wouldn't blame them, most people CAN tell the difference if they are listening on a good enough system. I don't think i'd be able to tell the difference with earphones, but with a good system I definitely can.
