Not so good

Its good, a lot of songs...BUT the fact that all the songs are always videos and you are downloading the video to play it Its equal to more battery use even if you are just listening with your iPhone locked and your device will be off sooner and more internet consumption because videos are heavier, you should have an option with just audio like Spotify, and offline option to use it where you have weak or no internet connection like in a plane or in another country would be nice.
