Python script to export tagged albums purchased in iTunes on an iPhone to PC. The script will rename purchased tracks from the strange 4837260613109701064.m4a format to human-readable filenames in the form: album artist/album title (year)/trackno - artist - track title.m4a (e.g. 01 - Rammstein - Sonne.m4a). It will also embed the cover art and a…
