BEST AUTOTUNE APP EVERRRR

Plain and simple. I had an iPhone 4S back when I bought this app. Now that I upgraded to another iPhone the app WONT PLAY MP3s ON iPHONE 6.
After that I HAD TO GO BACK TO MY iPHONE 4S to just simply download iAmTPain and record over the track that I wanted to.
If theres someone out there that can make this app able to record over purchased tracks big thanks! Anyway iPhone 4/4S buy this app!!
