By chance, has anyone ever heard the alternate feed of FM1 Muzak. Occasionally, the main signal goes out and then it'll be dead air for a minute or two, then totally different music (of the softer hit variety) will come on instead. Also, there are 2-3 second gaps of dead air between songs, unlike the regular feed, where one song blends into each other.
I've heard this feed before and there are some very interesting songs that normally you'd rarely hear in a business today.
Theme from "Summers Place" - Percy Faith
Why do Fools Fall In Love - Frankie Lymon & Teenagers
Sunshine Superman - Donovan
The Coast - Paul Simon
Do You Know the Way to San Jose - Dionne Warwick
Raindrops Keep Falling on My Head - BJ Thomas
Natural Woman - Aretha Franklin
And a string of songs from 1981.
Just too many to list here
