On Wednesday, Apple released an update to iTunes (US) that added DRM-free AAC music files to the iTunes Store. Dubbed iTunes Plus, the new version of iTunes will allow you to either download DRM (Digital Rights Management) files for the standard $0.99 or spend $1.29 on DRM-free songs.

In addition to iTunes Plus, Apple added a new section to iTunes 7.2 called iTunes U, where you can download lectures from various universities around the US free of charge. In addition to lectures, many Universities are offering language lessons, lab demonstrations, sports highlights and campus tours. Participating schools currently include Stanford University, UC Berkeley, Duke University and MIT.

It’s probably only a matter of time until someone claims that they graduated from “iTunes U.”
