You have to buy play back.

I bought this app despite the fact that there are lots of free ones because in the description when I looked at the In App purchases nothing showed up. I thought this app was everything I needed. No ....if you want to play back you have to pay for it if you want to convert to MP3 you have to pay for it the list goes on and on. This is for an app that already costs . I want my money back
huge rip off ....sleazy.
