I mean the 1970s, especially the mid-to-late '70s, for pop music. Of course there was a great deal of excellent music being made at the time, but most of it didn't make it onto top-40 radio. Because of my circumstances at the time, I didn't hear much else, and for the most part it was pretty grim.
I hated every song in this list, with the partial exception of Ringo's "You're Sixteen." Ringo did not, as the video seems to assume, write the song. It was a hit for somebody or other in the '50s, and it was not the only song of the time that saw nothing wrong with the singer being in love with a sixteen-year-old girl. (See the sweet "Sixteen Candles.") Many or most people got married before they were out of their teens back then. I agree that it's creepy for a middle-aged man to be singing it, but the song itself is not intrinsically awful.
I may have miscounted but I think there are only nine songs here.
Here's the Billboard Top 100 of 1976. Without going through it and counting, I'll guess that for me it would be a roughly 50-25-25 split: "strongly dislike," "not bad," and "I like it." Looking ahead to 1978, it might be more like 80-10-10.
I strongly suspect that today's radio pop is worse than ever, but I don't hear enough of it to be confident in that judgment.
