I used to be picky about audio quality having to be unbelievably good.  Not nearly as picky now.  MP3 is just fine, thank you very much.  It's all about the music and remembering being in the third row for Steve Miller Band and the Sons of Champlin and ... in the late 60's.  Wolfgang's Vault has to be one of the best, and best-managed, web sites on the internet.  Thanks so much!
