We were one of the families who were there. We surprised our 10 year old son and 13 year old daughter. It was their first big arena show and they LOVED it. You nailed it. It's music they can enjoy with their mom. They are still developing their taste in music, they are not as jaded or even as familiar with how cliche some of the lyrics and whoa-oh's can be. They hear a steady beat, a catchy tune and lyrics that somehow mean something to them. And from an adult perspective, it's pop music that doesn't make me want to tear my hair out, the lyrics aren't violent or misogynist or overly sexualized, so I'm ok with my kids memorizing every word. So I love them. Not because it's the best music ever, or even because it's my taste, but because it's something fun in a fragile world, at a fragile point in my children's lives that we can share and dance and stomp and sing together and forget about crap for a while. You can't put a price tag on that.
