Right another app i thought id share with everyone here Usb Audio Player Pro 3.3.6 and usb audio player patcher
install UAPP 3.3.6 close from multitasking run usb audio player pro patcher, click patch you now have the most recent version of the app
also one thing, if you have freedom.apk ( in app purchase hack tool) installed Usb Player Pro picks up this hack tool and wont run ( even before patching ) until freedom is uninstalled if you have lucky patcher this will be fine
