re:

Have you tried resetting your phone (hold down the Home and Power buttons a the same time and continue to hold until the Silver Apple appears). Once the Home screen comes back up, see if your Music is OK.

If it is not, then, have you sync'd your phone to an iTunes library on a computer? If so, then hook it up to the computer, uncheck the "Sync Music" option so that no music is sync'd and then sync the phone. This should delete everything on the phone. Then go back and re-check the "Sync Music" option, and select any other criteria you want on that screen, and then sync again. This should put back all of your music.
