Garageband saying songs I am trying to import aren't audio files
Every time I try to move one of my songs over from iTunes into GarageBand on my Macbook Pro it says it is not an audio file. However all of my songs are mp3. I have searched for how to fix it all over Garageband and tried to find help online. Please help me try to figure out how to get my song onto Garageband to edit. I've tried everything!
