Music stops playing

The music stops playing when you exit out of the app!!!! Why in the world would you set an app up like that? The previous one still played regardless on or off app. Its so frustrating when youre working out and trying to respond to a text but the music has to stop playing. Stupid stupid stupid... Now all I use is Soundcloud for music but I liked Playtube better because its the songs I choose with variety.
