great app, new version has issues

I love this app, but the newest version has issues with the offline cache. It used to be that if you streamed an album that you already had some songs from in your offline cache, it would play the already cached tracks from offline storage and only stream the songs you didnt have cached. In the latest update, it streams songs even if you already have them cached locally. This means that my data usage is much higher (I exceeded my bill last month), and it also irritatingly downloads double copies of songs to the offline cache that I have to manually delete. This needs a fix.
