So i found out the easy way of recording a voice with instrumental music on garageband but what would be the best thing to do if i wanted to have three people sing together? I used headphones so i didn't record the music along with my voice. Should i just go ahead and huddle everyone in front of the computer without plugging in the headphones to let the music play aloud (i will be using the inSight camera to record since i don't have mics)?
