iTunes on iOS 7 Crashing Since Friday 9/20/2013, when I try to open iTunes on my iPhone 4s (running iOS 7), it crashes.  I was able to open it to do a search and purchase a song, but after it started downloading, it crashed.  Every time I try to re-open it, it crashes after a couple of seconds.  I've tried unloading it from memory and that doesn't fix it.  I also completely shutdown and powered on the phone, but that doesn't fix it either.

I can't believe completely wiping my phone would be the only way to fix this; any other suggestions?
You don't have many other levers other than a full backup and I erasing all content and settings as a general remedy, but I would probably try the following for resorting to a wipe:


Check the usage and delete some content so that you have at least one gigabyte of free space
Signout of iTunes Home sharing and iTunes match
Sign out of the App Store
Make sure the date and time are set correctly or automatically set
Put the device in airplane mode, then power down and start back up while in airplane mode


If the music app is still misbehaving after removing all the network influences it might be something about your iTunes library on the device. You could also try using iTunes to blow away all the music. 

Also, since you just made a purchase from the iTunes stores, Apple support should be able to help you with that purchase (and the problems using it as a result of the purchase).  http://www.apple.com/support/itunes/contact/
