Hi there, about 2 weeks ago, my phone started using TONS of data. I finally discovered that Spotify is the issue.

I am always careful to download albums/songs to Spotify while on Wifi before playing them if I'm leaving the house.

My Starred playlist is 100% downloaded to my phone. I just played 3 songs from my Starred playlist (again, both songs are downloaded to my phone), and my phone registers that Spotify has used 205MB of data in the last 10 minutes. I can go into Airplane mode and the songs keep playing (as proof that they are downloaded). What is Spotify using all this data for?

How can this be? Please help. I've had Spotify on my phone for about 4 years now and have never ever had this trouble.
