LOL - that explains it. I wonder if SAM is even recognizing it as an mp3pro file, since it sounds exactly like what you'd get by listening to mp3pro with a non mp3pro player. It's probably interpreting it as an mp3 file.

But if you've converted it to mp3, then double check that it's an actual mp3 file, and not mp3pro. Or there might be some other conversion problem in general if it is indeed an mp3 now.
