Guys I have resolved the issue price field is not in my module. I have added audio_file_item_price and it is working and do some modification in skin also.
but we need to to apply distribution license depend on countries so there is any event to modify the item_price.
I have configured the foxycart module but add to cart button is not displaying on media for single song purchase. Foxycart bundle is working fine.

I am getting error "invalid jrCore_checktype: split". When custom "checktype (agree and split)" is added into custom module and when we activate the "foxycart" module then these "checktype" is
not loaded into "jrcore_checktype_cache".
yes this is a custom checktpe I have added in module init function,
