Want to strip that identifying marker off your files without losing any info by compressing it to MP3? Here’s how (at least on a Mac, although I’m sure there’s a easy way in Windows to do this as well):

Step one: In your iTunes preferences, under the advanced tab, choose to import your tracks as Apple Lossless.
Step two: Highlight one of your shiny new DRM-free tracks
Step three: Click the Advanced tab in the menu and select “Convert Selection to Apple Lossless”

Bang. You’re done. No quality loss, no iTunes account info. You can verify that your ID has been stripped using the Get Info command, or via the Unix grep solution that TUAW suggests above.

I haven’t tried it yet, but it wouldn’t suprise me if it is that easy. Drm and all of this stuff only stops the people that it is not intended for. hahaha
