How can I make beaTunes analyze protected tracks?
There is no easy way to achieve this. DRM protected tracks cannot be analyzed. The reason is obvious: If beaTunes could easily access the raw audio data for analysis, it could just as easily create an unprotected copy. With the exception of iTunes Plus songs, all songs purchased from the iTunes Store are DRM protected. As a DRM-free alternative to the iTunes Store you might want to check out Amazon’s MP3 store.
