//priorities:
//todo:
//-sample loading partially implemented, will do later (now is 21/01/04)
//-make songs fade in & out - add query/callback for end of song so that they can cycle
//-make samples sound from mapwindow
//-make samples fade in & out according to distance
//-try and use original .m files
