Yeah, it’s a bummer all around. A few of the songs were recorded and mixed here, so we can remaster those. She may have some pre-mastered evaluation mixes of some of the others that are of better quality. I don’t know what I’ll do with the rest…
I was going to mention this as well. You may be able to use Audacity (with the appropriate plugin) to conver them to WAV. You can also use Audacity’s “spectral analysis” feature (I think that’s what it’s called) to see if it is lossless or not.
