I'm wondering if it's possible with Garage Band to edit clips from commercial CDs? I want to lift segments from several different tracks on commercial CDs (the individual tracks are in my iTunes library if that makes a difference) and create a medley track. If this can't be done in Garage Band, what is the best tool (and cheapest and easiest to learn -- this is strictly a one-time project) to use? Any advice would be greatly appreciated.
