iTunes Match and iOS device storage When I enabled iTunes Match (which is generally brilliant), it wiped my iPhone's music library as I expected it to, but it didn't wipe my iPad library. 

Now that I've got iTunes Match working so nicely, I want to reclaim the space from the music I was carrying around in case I wanted it. But I can't find a way to bulk-delete music either on the device or from iTunes. Now that it's Match-managed, iTunes shows my music listing greyed out and uneditable. On the iPad I can delete songs one by one, but that's not what I want.

How can I wipe clean an iTunes Match-driven music library on an iOS device?

Wait for the storage amounts to load then click on Music and swipe left or right.  It will delete all the music on the iDevise in on fell swoop.
