Love the music variety and app. Although buyer beware the download while on cellular data toggle is very buggy and while I had it set to off the app downloaded 7 GB worth of music to my phone before I got a notification from my carrier of high data usage. Never really been an issue until the last couple of updates but could cost someone alot of money luckily I have 8 GB worth of data or that could have cost me $700 (my carrier charges $10 per 100mb after limit). This needs to be fixed!
