Never allows me to play my music – Walkout Song DJ Review

I bought the app and everything works fine until I close it , as soon as I close the app everything is unable to be played and I really Enjoy this app just quiet annoying . I get all my songs for all my players on and then I close it for the next game and boom it’s unable to play all of a sudden . Please fix
