Bring back old version!!!

I used to love this app! I rated it 5 stars in the past but my opinion has changed. Ever since it was updated I can no longer listen to the music unless I have the app open. Whats the point? Please update asap! I recommended this app to all my friends and family because I was very pleased with it but have currently been hating it! Please make these changes soon!
