Does it seem that concert goers just don't get into as much as they did in the 60s and 70s? ?

Hi. If you watch a rock concert nowadays,the first two or three rows
of people are really getting into the music,headbanging,air guitar,all
that. But past that,people are just standing there with their
phone,looking bored. But when you watch a concert from decades ago,
mos of them are going wild,jumping around etc. I'm not talking about
any band in peticular,but it seems with every band nowadays. Thanks x
