I mean, it wasnt really meant to be competitive. The artist made it that way. Like the jill scott vs badu. They were showing love to each other so the vibe was dope and different
Also, being an artist is about your recordings and performance. If you are a singer and i go to your concert but I find out you really cant sing live, you lose credibility with me. If you a rapper and you dont know half your lyrics and just walking around the stage, probably be the last time I see you live. It is insulting that they can charge you mad money at the concert but show up half assed. That is why out of the dozens of rappers I enjoy listening to, only few a would go and actually see.
