Hi Jazzguitar,
I'm sorry about the inconvenience and thank you everyone for the advice.
I have one more tip before reinstalling the app.
Please check that your In-App purchases are not blocked in the Settings > General > Restriction.
Do you have a backup of your songs? I've just tested the update with in-app purchase on iOS 7.1.2 and it worked fine.
What kind of device do you have? Try to connect your device to your computer, open iTunes and then open the app.
Let me know if any of these helped.
