Well, it may be true that with DRM they're giving away the key as well, but
that's not the way ALL DRM works. For example, the Windows Media DRM has a
key of some sort embedded in each player that supports it, which is why the
H300s lose the ability to playback DRM'ed music once the firmware is flashed
to an international version, and it's non-recoverable. So, while some
methods of DRM aren't "strong" the main reason that they aren't is because
if the algorithm were revealed you could permanently decrypt your music,
rather than only temporarily for playback.

Goldwave actually uses the audible directshow filter. For all practical
purposes it plays back the file, then records that playback as a WAV, then
gives you access to that rather than the original file. But all this happens
internally. Your computer has the ability to play the files, but that can't
be done on various MP3 players, as within Rockbox they don't have the
ability to play them back at all.
