Needless to say, an interesting hobby.
I remember the late sixty’s, early 1970 songs played on Armed Forces radio in Naha Okinawa from 69 thru 70.
Back in 1971, my musical tastes still centered on the Partridge Family, Osmonds and Jackson 5. But I remember a lot of the other hits as well as my mother had Top 40 radio on all the time.
50 years ago this week, the Osmonds "One Bad Apple" replaced Dawn's "Knock Three Times" in the number one slot on the Billboard Hot 100.
So I've been basically building a playlist of music from exactly 50 years ago. Just like Casey Kasem, I drop a few each week and add new ones. Except I look at the Hot 100 - not just the Top 40. I also explore album cuts that were playing on AOR radio at the time.
I'll probably maintain this hobby until I die. Fortunately, I'm likely to be dead before I get to the period where everything turned to crap. But in meantime, still a few decades of great 50-year-old music ahead of me.
