If a song is on your iPad, and pressing play does not play the song, the app may have not yet recognized the song yet. This problem may be fixed by closing and reopening the app.

To close and reopen the app:

a) Exit the app by pressing the iPad home button.

b) Double-press the home button to open the iPad navigation menu.

c) Press and hold the app's icon. Within a few moments, an X will appear in the upper left-hand corner of the icon. Press this X to close the app.

d) Reopen the app by pressing the app icon on the iPad home screen.

If closing and reopening the app doesn't fix the problem, there may be another issue. The app recognizes songs based on their title, artist name, and album name. If these things do not exactly match what is listed in the app, the song will not play as it should.

You can change a song's information using iTunes on your computer. Once its information has been changed to exactly match what is listed in the app, add the song to the iPad again, and try to play the song through the app.
