I bought Ben Folds's new album, Songs for Silverman, but I had to return it because it wouldn't play on my computers at home or at work, making it mostly worthless to me. It wouldn't play because it doesn't conform to the Compact Disc specifications. It is a DualDisc.
Supposedly DualDiscs exist to add DVD-like bonus features to CDs. Videos, interviews, that kind of thing. In particular, Silverman comes with a copy of the whole album in 5.1 SurroundSound—a phenomenally cool feature, if I had a SurroundSound home theater, which I don't. But really DualDiscs exist to fight music piracy. I know this because Songs for Silverman isn't sold on CD. This really drives me crazy, since I don't pirate music and haven't for years. I can't even buy an album I like and listen to it at home anymore. Technology sucks.
I'm particularly irritated at Sony because the fact that the disc was not a CD appeared in print about 1/8-inch high on the back of the CD. Barnes and Noble graciously gave me store credit when I returned the DualDisc, even though I had already opened it. I hear some record stores don't do that. They all should; it's borderline fraud to put these non-CD things into CD cases and sell them alongside CDs without warning your customers.
