Here are the five most popular songs in the Billboard Hot 100 Pop Singles Chart, for the week ending July 23, 2016.

The chart has been kind enough to give us a new song this week. This one's a bit of a reclamation project.

Number 5: Sia Featuring Sean Paul "Cheap Thrills"

Sia kicks it up a slot to number five with “Cheap Thrills” – the remix features Sean Paul. When not writing songs for herself, Sia writes them for other acts…who nonetheless sometimes turn her down. “Cheap Thrills” was rejected by Rihanna, so it ended up on Sia’s latest album This Is Acting.

Turns out there was a bit of role-playing in our next song as well.

Number 4: Calvin Harris Featuring Rihanna "This Is What You Came For"

Calvin Harris and Rihanna strengthen a slot to fourth place with “This Is What You Came For.” If you look at the song credits, you see that Harris co-wrote this song with someone named “Nils Sjoberg.” It turns out that “Nils” is none other than Harris' ex-girlfriend Taylor Swift. They split in June after 15 months together. Going forward, Swift will receive songwriting credit under her own name.
