Thought I’d post this tip to those not wanting to use or having problems windows media player or any other media player. I used winamp and it worked great.
Download winamp version 5.52. Copy your music files into the audible directory of your m240. (you can even create a folder with your files). Then load winamp. Add files to your winamp playlist from your m240 audible directory (just use “add Dir”). Click on “PL” to see your playlist). Then save your playlist under “list opts” of your winamp program to the audible directory. Don’t save the file to the sub directory you created in the audible directory. Unplug your m240 and you should now be able to view your playlist. I just created two directories with different music files and it worked perfectly.
