Spotify, it's very good music app although their is some problems, like when it says you can get 30 minutes off ad free music after I get an add, but two minutes later I get an ad, second problem is that the music just stops randomly and it gets annoying, and last when I stop a song and my device turns off, when I turn it back on and I want to replay a song it dosent let me, only says to skip, even for play list it only shows the song name, dosent let you play it when you tap on it.
