Yes. Garageband accepts several file types, including AIFF and MP4.

You can just drag an iTunes copy of the song in question straight into Garageband, and edit out the parts you don't want.

Without getting into the whole lecture, you should OF COURSE be aware that you can't really use other people's copyrighted material in your own project for anything other than personal amusement without permission and payment.
