In baseball, it amazes me how stats are kept on everything. How many pitches thrown in a game, in a series, in a season and in a career. How many fly balls are caught, how many base hits are made, how many fouls. They probably even keep numbers on how many times a pitcher spits or something silly like that. Stats are kept so that progress, growth, and success of teams and players can be tracked and recorded.
What if we thought about worship song sets the same way?
