One thing about this list is the high quality of the also-rans: there are lots of really good pop songs on this list. When you flip forward to 1968 and see a lot of the junk on that list, you’ll know what I mean.
The two Monkees songs are both good, ditto songs by the Box Tops, Turtles, Rascals, Supremes, the Association, and even the Strawberry Alarm Clock. The only song on the list I wouldn’t want to hear is the Sinatra duet.
