Thank you for your patience.
We worked with customers that experienced this bug, identified the cause, then fixed it.
You don't need to wait for the update. The bug was associated with several songs. Our sincerest apologies.
Here's what to do:
Write down your username and password.
Then delete the app.
Restart your device.
Then reinstall.
Re-login with your username and password.
That should do it.
