As a lead singer I find it very annoying that everyone wants multiple songs, to the point where I’m singing maybe 25% of the songs? I’m fine with sharing the leads but I’m basically a backup singer now, not a lead. I’m just so curious what compels everyone to sing when they already have their part (drums, guitar, etc.) Why not just be a singer then? Also when sharing leads, why are other leads such hogs? They want 80/20 not 50/50.
