[Windows Phone] How to delete the cache?

[kanrakuu]

Is there a way to delete the cache, either within the app or manually? It just grows and grows, and doesn't even give any useful functionality anyway, since it doesn't indicate which tracks are cached, nor do they show when you go into offline mode.

Requiring users to repeatedly uninstall your app to keep it running doesn't seem like a very good idea. One day they might not reinstall.

more than a year later it is still the same... no cache clear, just uninstall/reinstall... I think this is no user friendly feature...
