First time user, trying to import spoken word mp3s that are on my desktop into Garage Band so I can edit them. Thought this would be simple, must be missing something. I drag into the track or space, I see an 'importing' message for an instant , but nothing appears in the audio track. and/or no new track is created. These mp3 tracks are 44.1 , and play fine in iTunes. Can't figure out why they won't import. help, please.
