Can music recorded with garageband be saved as mp3?

Yes ~ Click Edit under My Music, select the music to export, and then click the icon like Enter. There is a drop-down menu, select Export to itunes, then select itunes, select the format to export, and then go to itunes to find the garageband program documentation and export music. At this time, the format is not mp3, but Apple's own format, which can be converted into MP3 with software such as Format Factory.
