I know the question wasn't addressed to me, but I'll throw one out there.

I use iTunes to organize all of my music (and buy much of it). After purchasing in iTunes, I strip off the DRM and convert to mp3 so I can use my music on all my devices.

Then, I tag them with a program called MediaMonkey. The reason I use MediaMonkey is that it can automatically grab the album art from Amazon and embed it in the id3 tag. iTunes doesn't embed the art in the tag, so when you copy some files to another computer or device, you have to re-download all of the art. Dumb.

Once I've tagged my files with the art, iTunes will happily read the artwork from the id3 tag (although it won't write it to the tag.)

Are there any suggestions for native Mac tagging utilities that will pull album art automatically and embed it in the id3 tag? If not, I'll just run MediaMonkey with Parallels.
