When I use the freedb option, I find all my track numbers lose the preceding zero (01 becomes 1 etc.).
This is a problem for me as my files are arranged by name in the format [Artist] - [Track Number] - [Song Name] and each album has its own folder. If the preceding zero is dropped, then the files go in the order of 1 10 11 12 13 2 3 4 5 etc
