So we got curious. When this year's playoff teams were last No. 1, what was No. 1 on the radio. We went to the Billboard music charts to check.
2011: The St. Louis Cardinals (and Texas Rangers)
Back in 2011, Adele's "Someone Like You" was No. 1 on the Billboard charts when the Cardinals beat the Rangers in a seven-game long World Series. It was the last time the Cardinals won the title. The Rangers are still looking for their first.
2005: Houston Astros
So like the Rangers, the Astros have been to the World Series, but they've never won it all. Their one and only World Series appearance was back in 2005 when they were swept by the White Sox. Kanye West was big on the radio at the time with his No. 1 hit "Gold Digger."
1993: Toronto Blue Jays
The Blue Jays won the World Series back in 1993 while Mariah Carey's "Dreamlover" was the No. 1 song on the radio. This is the first time Toronto's been back in the playoffs since that title 22 years ago.
1988: Los Angeles Dodgers
The Los Angeles Dodgers may be blue, but it was UB40's "Red Red Wine" making the rounds on the radio the last time the Dodgers won the World Series. The 1988 No. 1 song is a reggae fusion remake Neil Diamond's song with the same name.
1986: New York Mets
The Mets beat the Red Sox in a seven-game series back in 1986 for their last World Series title. It was also the last time any of Cyndi Lauper's songs were No. 1 on the Billboard charts with her hit song "True Colors."
1985: Kansas City Royals
The Kansas City Royals may be this year's No. 1 seed in the ALDS, but they haven't won a title since 1985 when they outlasted the Cardinals in a seven-game series. At the same time, Whitney Houston was also No. 1 with her song "Saving All My Love For You."
1908: Chicago Cubs
If you're a Cubs fan, it hasn't been a kind 107 years. That's how long it's been since the team last won a World Series title, coming back in 1908. That's well before Billboard even existed, but it was the same year the classic song "Take Me Out To The Ballgame" was written and composed. Perhaps it'll finally be the Cubs year. After all, Marty McFly spotted the Cubs were the 2015 series winner in the 1989 film "Back to the Future Part II."
