Realizing concert photography is exhausting

I have been shooting concert photos anywhere from monthly to a few times per year since about 2017. They're all for this company that owns a few big venues in my city. They don't pay, but I get a free ticket and I get to be super close and capture/share images of very famous people. It's an ok deal, nothing great but every once in a while it's fun.

I was shooting at a big name rap show last night and after looking through the photos today, I'm just like... why do I do this?

- The lighting is usually terrible. Maybe it's a me thing but even using custom white balance with a card, the colors are all over the place and require major work in Lightroom afterwards
- The crowds are not good
- 3 song limit... why?
- There's an incredibly low amount of music publications that will credential you, so the opportunities to shoot are MUCH lower than, say, a sports event where lighting is usually very good and everyone is professional.

I mean it isn't a big deal, I will just stop taking the gigs if I really don't like it anymore. But I just wanted to discuss this type of photography as being possibly one of the more frustrating ones.
