If your mp3 player gets the order of the songs wrong, then you need Song Renumber. It will automatically fix the problem three ways. First it can add sequence numbers to the file names. Second, it can fix the date stamps on the songs. Third it can copy the songs in the same order that you are looking at them. With this, you won't have to re-rip, which you may have noticed is the next best method. The next time you stream rip 8 hours of Internet radio and forget to add sequence numbers to the files, you will wish you had Song Renumber.
