Interestingly, last night (The 4th of July) I attended a BBQ where the average age was high-20's, low 30's and would you guess what music was on all night long? Sirius/XM's "40's on 4". Nobody was dancing (it was probably still in the high 90's even after dark) but the music seemed popular.
We had a block party in my neighborhood recently. Ages ranged from teenagers to retirees. My neighborhood has about as diverse a collection of people as you're likely to find anywhere. Let me describe the neighborhood by the ethnic foods people brought. We had kimchi, sushi, halushky, pork BBQ, potato salad, chili, tacos, hamburgers, jambalaya, chitterlings, black beans & rice, gumbo, crawfish, pad thai, and more! I was in charge of background music, so I but together the biggest variety I could from my MP3s. The crowd favorites were Cab Calloway's "
Minnie the Moocher", and almost everything I had by by Big Bad Voodoo Daddy, the Cherry Poppin' Daddies, and the Squirrel Nut Zippers.
I think I ended up giving half the people there SD cards with all the songs that they heard for the first time at that party, from almost every genre of music. That's not an uncommon experience for me. The Mexican family from two doors down had never heard "
Eres Tu" by Mocedades or "
Guantanamera", by the Sandpipers. The young Black family from across the cul-de-sac had never heard Ike Turner's "
Rocket 88". Neither the Russian heavy metal fan nor the Japanese Sushi chef had ever heard anything by Japanese metal band Ancient Myth, but they liked the songs by them that I played. I think I turned several different people into Blues Project fans.
It's experiences like that which convince me that it's total BS when the suits claim people only want to hear songs they already know from when they were in high school. I've had too many real life experiences that say otherwise.
