What they're looking for is songs that won't cause too many people to switch stations, and that includes songs that work well in an office or waiting-room setting where a supervisor or a doctor controls the radio.
I sure don't know about that. I have never heard an Oldies station playing in a doctors office or other "quiet" waiting area. Most times it is AC (MOR) or non-nondescript instrumental. Places where Oldies rule are drive-in's, home improvement stores and casual dining restaurants.
What sets them apart from mainstream AC stations is that just about all the music has to be at least 25 years old, so what's desired is older songs that still do well with people in the lower end of 25-54.
Wait! The math doesn't work here. A 25-year old song is a song that most 25-year old's haven't heard and probably wouldn't like (according to resident experts although I find plenty of exceptions to that). If you want people to like Oldies the age range is more like 50+.
When's the last time you heard anything by Pet Clark besides "Downtown,"
Never. She's pretty much a one-hit wonder and that particular song is 45+ years old.
anything by the Rascals besides "Good Lovin'," anything by Tommy James besides "Mony Mony"? Ten years ago, "My Love," "I've Been Lonely Too Long" and "Crystal Blue Persuasion" worked on oldies radio. With '80s and late '70s songs occupying a greater percentage of the music slots at classic hits radio, there's no longer room for those secondary and tertiary titles.
Wait! Were we talking about Oldies or Classic Hits? British Invasion music would be Oldies. I wouldn't expect to hear it on a CH playlist (although it would be OK by me if it did).
