You can also get rid of SlotRadio by going back to Settings/System Settings/Rest Factory Settings and then making your region Rest of the World instead of USA.

has an Auto-Numbering Wizard under Tools (you have to have the tracks highlighted). Make sure they are in playing order, top to bottom, and run Auto-Numbering Wizard with Leading Zeros checked. You don’t even have to Save after that–you’re done.
BTW, if you look at the files in Windows it will still show them numbered 1, 2, 3, even if you give them leading zeroes. Don’t ask me why–it’s some Windows things. But if the track numbers are 01,02, etc. in the tags, they should play right.
