I don't really care about the format but I thought part of the point was for Mudcat to make some $$$. If you do MP3 that won't happen. I personally can't afford to buy more than 2 at a time but I would eventually buy them all. MP would be nice because I would listen at my computer, but the speakers are not loud enough to hear anywhere more than 4 feet from the computer and I can't as yet burn CD's. Burning your own seems like ripping off Max anyway. He has provided this forum and opportunity; seems only fair he should get something back.
