But you are forgetting that people who come to gold based stations expect familiarity. When they hear unfamiliar music, the station is basically breaking a promise of providing familiar favorites. When a station fails to live up to expectations, listeners leave.
If the gold-based station changed completely from a song list like this:
Le Blanc & Carr - Falling
Savage Garden - Truly Madly Deeply
Bette Midler - Wind Beneath My Wings
Elton John - Sorry Seems To Be The Hardest Word
Stevie B - I'll Be By Your Side
Ambrosia - You're The Only Woman
The Eagles - Best Of My Love
REO Speedwagon - Can't Fight This Feeling
Bonnie Tyler - It's A Heartache
Ronnie Milsap - There's No Getting Over Me
Olivia Newton-John - Hopelessly Devoted To You
Foreigner - I Want To Know What Love Is
Cliff Richard - We Don't Talk Anymore
Michael Johnson - Bluer Than Blue
Art Garfunkel - Since I Don't Have You
Celine Dion - My Heart Will Go On
Mariah Carey - Visions Of Love
LeAnn Rimes - How Do I Live
Jim Brickman and Martina McBride - Valentine
Faith Hill - There You'll Be
to a song list like this:
Maroon 5 - Daylight
George Michael - Father Figure
Nickelback - How You Remind Me
Katy Perry - Teenage Dream
Kenny Loggins - Footloose
Aerosmith - Cryin'
Bon Jovi - Wanted Dead Or Alive
Prince - Kiss
Black Eyed Peas - I Gotta Feeling
Fun - Some Nights
Cee Lo Green - Forget You
Kelly Clarkson - Behind These Hazel Eyes
Shannon - Let The Music Play
Michael Jackson - Billie Jean
Carrie Underwood - Before He Cheats
Pink - Try
Eurthymics - Sweet Dreams Are Made Of This
T'Pau - Heart And Soul
Taylor Swift - Shake It Off
John Mellencamp - Hurts So Good
then I can understand (and sympathize with) the listener leaving. It's a huge change in texture of the station.
But we're just talking about a mix like this, only mixing in certain current songs that have a soft texture, which I very highly doubt would turn off a gold-based listener, and if it does, then that listener must be extremely picky:
Don McLean - Crying
Lonestar - Amazed
Carly Simon - Anticipation
Vanessa Williams - Save The Best For Last
One Direction - Story Of My Life
The Carpenters - Goodbye To Love
Adele - Someone Like You
Bee Gees - More Than A Woman
A Great Big World & Christina Aguilera - Say Something
Barbra Streisand - Guilty
Sade - The Sweetest Taboo
Lionel Richie - Hello
Pharrell Williams - Happy
Backstreet Boys - I Want It That Way
Josh Groban - You Raise Me Up
Enya - Only Time
Taylor Swift - Teardrops On My Guitar
Kelly Clarkson - A Moment Like This
Heart - Alone
Colbie Caillat - Bubbly
