Contacted Microsoft about xbox music and "other" storage issue

[HaibaneReki]

I didn't know that, so now I know that Spotify is taking 2gb's of "app data"... Any idea on how to get rid of it?(just deleting random music didn't work)

I'm afraid only a clean reinstall of the app will do it.. Just cleaned 500+ MB by reinstalling ProShot and HDR Photo Camera.
