In order to get mp3 files to burn in the order you put them in, you will most likely have to rename your files by adding 1 2 3 in front of the file name. Otherwise, an mp3 disk is a data disk, and data is stored alphabetically or numercially when numbers precede the title. I can't remember where I read the 1 2 3 tip, but I just live with my mp3 disks in alpha order rather than rename them every time I want to make a disk. Just press random when you're tired of knowing what's coming next.
