(Mac ONLY) Freeware app DRM Dumpster plugs into your iTunes music library, burns protected tracks to CD-RW, then re-imports them to your hard drive.
This is the good old method of getting rid of DRM music without cracking it, but this is one is nice and automated, and you loose nothing since you can use a CD-RW you can keep on reusing it all the time.
