The new iTunes has stricter DRM than the last version, limiting the number of times you can burn your playlists to seven (it used to be ten), and detecting and blocking similar playlists. Jason Schultz has some good ranty analysis about what this means:
So after one year and 70 million songs, $0.99 now buys you less rather than more — seven hard burns instead of ten soft ones. What will Apple "allow" us to do with the music we "buy" next year? three burns? one? zero?
And what about the songs you've already bought? Don't we get to keep the rights we had before the change?
Well, Apple has conveniently reserved its rights to make changes — unilaterially — to its DRM and your ability to make fair use via its Terms of Service and Terms of Sale pretty much anytime it pleases, without even having to give you notice.
