It's not very easy to tell exactly what you are buying at the iTunes store, or Naptster and other online music stores. People are jumping in with a lot of money under the impression that they own the music they pay for. But the EFF points out that this assumption is naive, and copy protection makes the reality quite different than the marketing sales talk.
For example, did you know that "For a monthly subscription fee, the Napster Unlimited music rental service offers you the ability to stream and download as much as you like from its entire catalog. If you miss a monthly payment, the DRM renders the downloaded music unplayable." Miss a payment and all that music you think you own is no longer available to you. You were just renting.
Get past the marketing talk and find out exactly what you can and can't do with the most popular online music services with the
EFF DRM guide.
