To B-Side or not to B-Side?

Well Tom Waits is out with a new CD. I guess it's not so much a new CD, it's supposedly a compilation of Rarities and B-Sides. The problem I have is that B-Sides and Rarities in music are usually not the greatest CDs, more like the leftovers. I did recently buy Bob Dylan's Basment Tapes, which I assume to be similar, I though the Basement Tapes were great. Tom Waits however is an artist in the truest sense of the word and I'm up in the air. I wonder what these songs are like: sloppy second takes? The shit that was so fucked up that the record companies wouldn't let Waits put it on a regular album? Club hits and remixes? I don't know, I'm really up in the air. Is it nobler to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles, and by opposing end them? To die, well, who can say really...

Waits! They don't love you like I love you.
