Don't know my stats but I'm using 50+ gigs on my Amazon Mobile app while working. Service provider bumped up my plan 20 gigs so now I have 70 gigs to work with and I figure that should be enough because 50 gigs wasn't quite enough. My Playlist is all the songs in my library that I rotate through, couple thousand songs. I Stream on my home computer as well but I'm saving my ears mostly for when I'm on the road and it's a motivator to work, so I can get my audio fix.
