They go there to express their passion, to show their idols how far they've come. See the point of idols is to give people hope, prop them up when they're at their absolute darkest moment in their lives, if you're strong enough, from that hope you find the means to go on, to no longer need them to prop you up anymore, but you're still thankful for what they did for you, and that's what these concerts are for.
You see them, they see you, look how far you've both come, now cheer with all your might.
Somewhere out there, an idol sings for all of us.
