This seems like some odd form of recycling. It's tunes like "Let's Get It On" by Marvin Gaye that help conceive the little ones in the first place. Apparently this particular tune, at least for the toddler above, can stop them from crying, and have quite the calming effect on them when it's played for them outside the womb.
I would stop here though. I'm not sure what adverse effects might come as a result of playing "Sexual Healing" for her... and that's just creepy anyway.
I've been in radio since 1981, starting on Cape Cod, and in Boston, Massachusetts where I grew up. (when The Sox and Patriots both broke everyone's hearts, and the Celtics ruled. Funny how things change.)
After 3 years in Las Vegas in the late 80's, early 90's I was looking for work and luckily found myself here in Cleveland in 1991, through some mutual radio friends. I got to play the hits as Jammin 92's Night guy until 1999.
After watching my former company screw up the "Jammin' Oldies" thing for a couple of years, I settled in at what would eventually become iheartmedia, and iHeartradio, playing people's classic favorites... the best decision I ever made!
