How do I change the info (artist,album,etc) on an MP3 file?
I am editing some mp3 files in GarageBand and I need to put in a different artist and album name. When I export the file from GarageBand and open it in iTunes it says that the artist is me and that it is my album. Any help on how I change it? I need to change the files properties and not just the name in iTunes because I need to upload it to the internet and so the artist name needs to be downloaded with it. I am running OS X Yosemite version 10.10.1, iTunes version is 12.0.1.26, GarageBand version 6.0.5 (428.5).
Thanks
MacBook Pro, OS X Yosemite (10.10.1)
