You'd be better off with an 00's portable CD player that supports MP3 playback. Much easier to manage music on something that isn't a complete technological dead end.
This actually seems EASIER than burning CDs.
Regarding music management, I've never seen any portable CD players that have any music management features, unlike MD recorders that have all sorts of music management features. However, that's not really relevant in either case as I manage my digital music library on my computer. With modern software, copying tracks to MD or CD is essentially the same: connect the device to usb and drag'n'drop the tracks.
