Tom Kielty holds up CD re-releases as a way that record companies abuse music fans.

[R]ight now, with the record industry reeling from slumping CD sales, the major labels seem eager to wring every dollar they can out of a superstar release...

I'd take that "right now" part out. There's nothing special about these days when it comes to record company greed. They've been wringing every dollar out of fans for as long as I can remember.

I still can't figure out the music pricing model. When I buy a CD, do I physically own that music to do what I want with it, or is it simply a license to play the music? If the former, what's the problem with sharing? If the latter, why should we have to re-pay for a reissue?
