Probably too much work; they just want to share the things they like amongst themselves I think. It's a great way to learn new music though.I have to say; you, in musical terms I mean, definately march to your own drum. Thats great; you like what you like.
But how can Van or Mick be embarrasments to music? What specifically would dictate that? I mean if we actually came up with an Embarrasment to Music thread it would be pretty long but I don't see it containing Mick Jagger. You may not like his voice but he never claimed to be Pavarotti. I like his early renderings of good blues tunes. He is one of the very few white guys who can do that well. Wild Horses? Thats a great tune. Lots of them.
