If you added songs to the device in MSC mode, then switch to MTP mode, you will not be able to see the songs added in MSC mode and vice versa, though the space used on the player will still reflect their presence. Switching modes should make the files show up. For example, switching from MSC to MTP mode or vice versa.

For older players - e200v1, c200v1, c100, m200 - the files become hidden files if the modes are switched. An easy workaround is to edit the folder options to show hidden files.
