This music app is completely amazing; and everything youd need in a music app. It has all the songs I want, and it doesnt need WiFi or Data to play them. Of course, you need WiFi or Data to add them to your playlist, but that is a given. I enjoy that they let you have as many playlists as you want, and as many songs as you want on a playlist, with a simplistic design that lets you play the music and exit the app easily. This app is very efficient on plane rides, or anywhere where you would like to listen to music. Ive never had any problems with this app and I hope they keep it the way it is, with no over complicated updates. I applaud the app, and I would highly recommend if.
