I love my Mojo. The ability to play disks of MP3s wherever I go is just so cool. I've got 159 songs on one CD and 138 on another. If you set up your MP3 disk with folders for artists and albums, the Mojo makes it really easy to  move around and play what you want.
A word about the FIF format: TDK talks a lot about "converting" your MP3 files to FIF, which scared me at first. "Converting" is the wrong word. FIF isn't a format; it's just a way of naming your MP3s so the Mojo can pick out artists and titles. The Mojo works best if you name your MP3s as "Artist-Title".  The Mojo comes with software to help you rename the files, but as you can see it's simple. Most people I know name their MP3s "Artist-Title" already.
FIF is how the Mojo can show you a list of the artists on a disk. It shows you everything before the dash (-) in your filenames. For song titles, it shows you everything after the dash. Works well, but the lists it displays are not alphabetical. I can't find any logic to them. If you've got a disk of 100 artists, it would really help to see them alphabetically, not a jumble.
One real downside to the Mojo is it won't play my Music CD-Rs well. I'm talking about CD-Rs specifically labeled "For Music Only," which I've burned with WAV files. I've got several Maxell ones, and they play fine in every device I have except the Mojo. I've been using these disks for a couple of years, but I'm going to have to switch to standard CD-Rs. I've heard that "Music" CD-Rs don't go through as much testing as multipurpose disks. The Mojo is probably picking up imperfections that all my other CD players don't notice. Multipurpose CD-Rs full of WAV files play fine in the Mojo, so just avoid the disks labeled "Music."
The Mojo could have used some flashier styling. It doesn't look year-2001 at all. But the 4-line display and simple buttons are better than most other devices of this kind. Exception: the volume buttons are up/down on the player, but the volume bar is left/right on the display. I'm always pressing the left/right buttons on the player to change the volume and accidentally changing tracks.
