Data usage

Hey everyone, generally how much data would be used in streaming music in the highest quality over LTE using Nokia mix radio? How much data for say a 2 hr movie.

I ask because there is no way I used 4 gigs in 2 hour. I have friends that watch movies, YouTube and listen to music all day almost every day and never use more then 4-6 gigs a month.

Thanks again.

No way just from music. Something else must be using a lot of data.

Its all at&t I gotta prove its not from my end. Just spent an hour on the phone now I got to fax this and fax that. Doesn't anyone use email at that place hahahah ugh fml
