The mp3 player is indeed not very intuitive. Like someone else posted, you cannot switch between the controls at the top of the screeen and the bottom of the screen once you move the cursor to the top row. The only way to remedy this is to fully exit the program and restart. A very annoying/unfortunate bug.

Adding songs to a list and creating a new playlist took a lot of playing around and button pressing, and I still couldn't smoothly create a list. The pocket-windows media player on PDA (HP) has a very simple but effective playlist creating process. Options to Create/Edit/Delete playlist, and once you click on the playlist you have the option to add/remove/move files. Click on ADD and it leads you to folders, click on folders and it shows the list of files where you can click the boxes beside each file then press ok to add the files.

Another nice option would be to be able to sort the list by Alpha, size, type.

Thanks and great work!
