I say f*ck playlists and PD's and digital tracking and automation. A human mind is a terrible thing to waste. Commercial stations should take a lesson from their non-commercial brother/sister stations "down the dial", or the model employed by alternative FM radio of the 60's by granting human beings the authority to produce their own content and listen to the fabulous results.
If you wish to hear this in practice, tune in to Eli Polonsky's "Lost and Found" -
http://lostwmbr.blogspot.com/ -Tuesday noon-2pm on student/community radio WMBR (88.1fm, streaming at wmbr.org) "Lost & Found explores music of the 1960's to mid-70's. We cover all genres, and spotlight music you won't hear on commercial "Classic Hits/Classic Rock" stations. Hits that have been forgotten, or the "hits" that never were!"
I guarantee you will not hear these 60's/70's titles played on sanitized commercial radio:
