I could be mistaken, but I think Bob wasn't happy with the first series (hence the move to WIPB) and didn't want the episodes re-aired. I have always assumed the muzak was part of it, along with lens flares, bad audio, etc. I'd like to think he had better musical tastes. Either way, it was something he didn't carry forward with further series, thanks be to God, because I'd hate to watch Bob on mute!
