Do you still have songs in your iTunes library that have the kind "Protected AAC audio files" and not "Purchased AAC audio files"? Sorry, yes, there is no way to convert these in iTunes
And there is no way to import these files in this Audio format into GarageBand '11.
I signed up for iTunes match, and this way many of the 128 kbps "Protected AAC Audio files" were replaced by higher quality 256 kbps "Purchased AAC Audio", which GarageBand can import. This will work, if the iTunes Store has a Purchased Version of exactly that song recording.
But we are not allowed to post here any methods to crack the digital right protection of iTunes media.
