Totally agree with you.. This is just the begginning..
Changing genre tags I figured is much harder. I have an auto tagger but it tagged my songs with over 50 genres. I only have a collection of around 1600 songs so 50 genres is quite ridiculous.
Covermess is operating the same way so I figure that you can get to features with one structure change. Covermess is a pretty cool feature and I use this as well. So the directory changes were actually a need.
