WOW! Your player supports all theese formats out of the box? Even ModPlug plugin doesn't support all of them natively out of the box but needs aditional plugins. That is realy awsome.
I gues I can scratch "making of my own module music libarary" from my ToDo list
Sure it will take me some time before I will actually need it but I gues I'll go with your implementaion instead. I will contact you when the time comes.

BTW Have you ever considered in packing the player engine into a closedsource component and thus making it more easily accesible to other pascal game developers.
