Well, a billion downloads were worth $1 a piece to somebody. However, its not worth it to me. I'm not paying $1 for a 192kbps song. I'd likely pay a buck if it were lossless though, even with DRM...probably only for singles that I wanted. If I want an album I buy it, new or used. CD's are likely to last longer than a hard drive, can be converted into any format you like and really haven't increased much (if at all) in price since they started coming out in the 80's.

And really, used at a local shop is a great way to support small businesses, hear some new stuff, and save some dough.
