I've in the middle of a project to put together a Spotify playlist containing every song to crack the Top 10 of the Billboard Hot 100 Singles chart, and for some reason I thought it would be neat to take a look at the #1 song in the country at the end of each decade.

So yeah, that's what this is for. Let's listen!

Last #1 Song of the 1950s: "Heartaches by the Number," Guy Mitchell

Last #1 Song of the 1960s: "Someday We'll Be Together," Diana Ross & The Supremes

Last #1 Song of the 1970s: "Escape (The Piña Colada Song)," Rupert Holmes

Last #1 Song of the 1980s: "Another Day in Paradise," Phil Collins

Last #1 Song of the 1990s: "Smooth," Santana feat. Rob Thomas
