Oldies have not been played out. Some have though. When you add up most of the Motown biggies along with major hits by artists with multiple hits (Four Seasons,Beach Boys, Beatles,Elton John,Sly Stone,etc.).Then add in a couple one hit wonder smash hits and before you know it, you have your "played out 500" song playlist.There are alot of memorable records that peaked between #10-#20 on the singles chart that have been neglected since they were currents. We are all aware that any single that peaked between #10-#20 received a substantial amount of airplay in most markets so they are not "stiffs". Since Oldies radio has their "chosen few" over the last 15-20 years, alot of these dormant records that were off the radar after they were currents are difficult to push on to the listening public, unless the ear listening in was into the currents back then or they are members found on this board.LOL!! In other words, the oldies format destroyed those old hit records of the past by not rekindling them when they should have. Lets see how many people will remember "Liar Liar" by the Castaways if that was thrown on, I doubt half the listening audience would even remember that record now, and it was a sizable hit in 1965 peaking at #12.
