Continuing a tradition that stretches back to her first world tour for Fearless in 2009, Taylor Swift's 1989 World Tour has featured a number of special musical guest duets, from a wide range of genres and radio formats. How did these guest artists benefit from their special appearances? The answer, like life, isn't black and white.

The biggest beneficiary of a Swift duet was former "Everything Has Changed" partner Ed Sheeran, thanks mainly due to his song choice that evening: X album cut "Tenerife Sea" saw a 39 percent increase in sales (according to Nielsen SoundScan) following its performance at Rock In Rio USA in Las Vegas on May 15, the opening night of the North American leg of Swift's tour. Aside from a 25 percent increase for The Weeknd's "Can't Feel My Face" (July 10 in East Rutherford, NJ) and a 14 percent bump for Jason Derulo's "Want To Want Me" (July 14 in Washington, DC), the other guest artists' sales increases were negligible.

Why wouldn't an appearance with one of the biggest superstars in the music industry at the moment result in more substantial sales?  Most of the songs performed were already established hits at the time they were sung on Swift's stage. While only one of the thirteen tracks -- Lorde's "Royals" -- was a Billboard Hot 100 chart-topper, the average peak position of the covered songs was No. 9. Swift isn't championing rising stars on this platform, instead turning to veritable hitmakers whose music she personally enjoys.

Much more noteworthy is the bump seen in social media engagement following the live performance and subsequent press coverage. Every single guest artist saw a sizeable bump in mentions on Twitter, and all but two (Nick Jonas and Sam Hunt, both of whom have large followings on the network already) experienced an increase in likes on Instagram, according to data compiled by Next Big Sound. Derulo received the largest Twitter gain in the week following his July 14 performance of "Want To Want Me," increasing his mentions by 737 percent; Little Big Town's cover of "Pontoon" led to the second-largest jump of nearly 502 percent. On Instagram, Rachel Platten, The Weeknd, and Andy Grammer all increased their likes by more than 200 percent.

By choosing guest artists who already have high profiles, Swift isn't putting lesser-known talent into the spotlight and boosting their sales among new fans. Rather, she is showcasing some of her favorite singles on the chart with the artists who made them hits. Considering her constant, lofty presence on the Billboard Artist 100 and Social 50 charts, it's only natural that sharing her stage would result in large social gains for her guests.
