So, I'm listening to SKY.FM...
SKY.FM's All Hit 70s, actually.
I hear the song, "Every Breath You Take" by The Police. I'm like, WTF...that's not a 70s-decade song. So I search on Wikipedia for The Police. I see that "Every Breath You Take" is a song from the Synchronicity album, which was released in 1983.
I thought so! I remember first hearing the song when I was a sophomore in high school. I'm not THAT old to be confusing that song with a 70's song.
Now I'm hearing on that particular station, "We Don't Talk Anymore", by Cliff Richard. That's a decade border song, as it was released in 1979.
