haha bestmates with djs, dno if this is already done, but a easy quick simple way if you have fl studio, whatever version
If you have a mic webcam whatever, say whatever you want clearly, save it to your comp, you can do this off wavepad or various other programs then edit it to make it sound how you like if your making your own music you can just sync it wherever u want, if not just play the hole song adding it wherver you want.
Once youve done that just go ahead, if your quick and your in a rush just do that put it on a cd and just mix it wherever you want it to go but i highly recommend dont do this way cous its too much stuffing around, hope it helped and if you need me to explain in further detail pm me lmao take care
