For any of the songs that are a problem, proceed as follows:

1. Copy the file from the flash drive to your computer's hard drive

2. Remove the flash drive

3. Right-click the file on your computer, and choose Open With > iTunes.

If the file is compatible with iTunes, it will start playing.

If it does not start playing, it is not compatible with iTunes.
