If you don’t know what DRM is, then you need to wiki it.
Once you know what it is, then you should consider the following New Year’s Resolution:
If you own an iPod, and you’ve ever wondered why you can’t transfer your songs onto it, the answer is most likely DRM. If you’re looking for an alternative to iTunes (all iTunes music has DRM) that sells DRM-free music that will work on your iPod, then consider Amazon’s music store. It’s cheap and DRM-free.
Okay, now back to work.
