I'm not 100% sure, because there are no mp3 on my collection,but making a backup of you library and then re-import that file on your device should clean unused files.
PS: my libraryis not so big (18.000 songs, 2.4 GbB size) but it runs flawesly in all my devices. A full sync between devices takes between 5 and 10 minutes, a local backup, usually, less than 5 minutes.
