I just went through the top 100 country songs for 1984, and my spidey sense says there's something funny going on, but I don't know what it is.
If I check out the artists I like from this period, no one seems to have a significant album from 1984 (Steve Young, Rodney Crowell, Billy Joe Shaver, Townes van Zandt, Ray Wylie Hubbard, Merle Haggard, Johnny Paycheck, and some others), it looks like a music desert for that year. Crowell, e.g. has "Diamonds and Dirt" from 1988, and "Houston Kid" from 2001). The closest I can find is 1983's "Pancho and Lefty," from Willie and Merle.
City of New Orleans: 82
To All the Girls: 80
Islands in the Stream: 75.
What's going on?
