How do i record them both At once so that you hear the song over the high sound of the drums tho and how wuld i be able to hear it so i can play to it??
It won't work. Did you read my post in the Q&A? If not, please do; I took a lot of time to answer your original question.
You have to have an audio adapter for your video camera that would allow you to input line level audio ... bypassing the built-in mic on the camera. If you CAN do this, then you take the pre-recorded audio and play it back via CD or computer. Output this audio to a mixer which you would monitor with headphones. You would have to have at least one or more mics for your drums which you would run to this same mixer. The main output from the mixer would then be sent to the video camera.
This is what I've done, which allows me to make my video lessons and content for the Drummer Cafe.
