Can't Install or update apps on iPod Touch 5g

Hi, i am having a very serious problem with my iPod. it is an iPod Touch 5th Generation, 32GB, blue. It is currently running iOS 8.2. The problem is, I can't install or update any apps. It just sits on the home screen grayed out and saying "Waiting...". It won't do anything else. I have already tried hard restarting it, along with signing out and back into the App Store. I have also tried deleting the apps and reinstalling, but it does the same thing.
