Confused – SongFlip Music Streaming Review

Ive had this app for maybe 2 years? And recently (after not using it for a long time) i realize that i cannot play more than one song if i turn my phone off because it just stops. I went to the app store and there was a download sign which is weird bc the app was already installed. I clicked it and now i have the app twice. The newer app is updated but for some reason the original app will not let me update?
