Update Broke Multiple features

I used the app before the iOS 7 update version of this app, Im running iOS 6 still.
What the update broke- that I know of that is, are;

Cant create playlists

Existing playlists dont show up

It only plays one song out of a album

Crashes more frequently

This app is a must have if you own the headsets that its compatible with! Please fix soon :) thanks in advance!
