That's the way that it goes. We perform miracles in raising our kids, get all sorts of accolades for being good in sales, as a Mom, etc, but nothing impresses the little ones like “We knew Mr Jonas when he was a worship leader”.
I'll tell you why the Jonas Brothers sell..... melody and lyrics. They can be heard. My son is starting to play guitar and likes the Beatles , John Hooker, and Albert King stuff I've got laying around. Cause he can understand the words and play along. The new stuff like rap doesn't lend itself to repetition, I can't see my self or I guess they can't see themselves humming along and singing "Gin and Juice".... or any of the current rap cr#p.
Something with a melody and lyrics sells cause others can relate to the message. That's why country is getting huge, jazz tunes like "That's All" and the blues will always be around.
Jeff Beck and Clapton still attract a crowd cause they're good musicians. click here.... Like Knoffler mixing it up with Atkins.. great musicians always have gigs. listen to the melody... timeless
