You ask an excellent question. I'm a 43-yr old MALE, and I'd occasionally like a place to turn where it isn't all *BANG-BANG-BANG-BANG-BANG*. It seems even the softer Sunday morning shows (great for those with hangovers from Saturday night) are gone.
Perhaps we have a society today that is "always-on" and has grown up with stress of constant push-push-push being the norm... they don't want to relieve the stress because they've never been able to relive the stress (through radio).
I was personally VERY excited about the NAC / New Age format when it was just coming up in the mid to late 80s... then it mutated to Smooth Jazz and lost some of the beauty to me, and then further morphed into a Soft R&B format, and has nearly completely died. (You can find sources on the net and on satellite, but broadcasts are few and far between.)
...And, perhaps part of the problem IS people like me, who want a "soft favorites" station as an alternative, a secondary listening station... perhaps people like me just wouldn't turn to it ENOUGH to make it profitable.
We just had a supposed "soft favorites" station come on in Tulsa... but if I were sick, or tired, or both, I would NOT want this station on... it sounds like an AC or even possibly a Hot AC.
I turn to the net to wind down... and even then, it's hard to find the "mix" I'm looking for, not even from Pandora or iHeartRadio.
(If anybody wants to set up a station running exclusively artists who were on the Narada label, you'd be an instant favorite for me!!!)
