Here's why Mariah Carey fans are thrilled about Taylor Swift's new single

Back in 1996, Mariah Carey and Boyz II Men's "One Sweet Day" spent a remarkable 16 weeks atop the Billboard Hot 100, setting an all-time record. Now, Luis Fonsi's "Despacito," which has occupied at least a small part of your brain all summer, is close to shattering that record -- but Mariah fans think there's hope for their elusive chanteuse.

And that hope, weirdly enough, is Taylor Swift.

Swift plans to release her new single from Reputation this Friday at midnight -- and there's a good chance it'll shoot right to #1. If it does, "Despacito" won't make it past its sixteenth week in the slot, and Mariah's record will technically remain unsurpassed.

Of course, a Tay #1 and a "Despacito" #1 aren't the only two options here. As Billboard points out, "Wild Thoughts," this summer's other ubiquitous anthem, has a shot at the top spot. (It's currently at #2.) So does Cardi B's "Bodak Yellow."

There's also the possibility that Taylor's new single is bad, thereby hurting its chances on the charts. But "Shake it Off" hit #1 back in 2014, so who really knows?
