iTunes Organisation Apps

Hi, I'm looking for an app to help organise my iTunes collection. By organising, I mean help correctly tag songs. So many of my songs have no title or artist or album etc, and I'd like to change this. I have bought an app called Song Genie which is meant to do this. It is largely accessible, in that everything is read out by VoiceOver, but I'm struggling to actually use the app. Has anyone ever used Song Genie with VoiceOver? I've also heard of Tune Up, MusicBrains and other apps that are meant to do similar or the same thing, but not sure whether any of them are accessible. If anyone has had any experience with these or similar apps I'd really appreciate hearing about it. Many thanks in advance.
