Yeah I regret the tone of my comment, sorry. I really wasn't trying to be snibby/elitist but I struggled getting my point into words. I will try again

"Barbershop has not just morphed and become other styles of a Cappella music like Pentatonix, modern barbershop is still barbershop, and exists alongside those other styles. If you are thinking the only modern remnants of barbershop is other acapella like Pentatonix (who are amazing btw!), I'm not saying you're dumb ...I'm excited to say that means you must be missing out on barbership itself still existing as a genre in its own right with a lot of fantastic music and artistry to be enjoyed".
