I just want you to know I love this program and use it every day. I do however wish that it did a little more library editing. Such as, if you have a specific thumbed down song in your library, it would delete that song. Which I would think is possible, however, due to permissions in Vista (Not sure about Win7) it could have problems deleting it if not ran as admin.
This is an awesome program though, and I greatly appreciate you creating it for free. Keep up the good work ^_^
