Remember when Alanis Morissette made dance-pop? And, when Katy Perry was Katy Hudson, Christian music artist? We have the proof.

Welcome to the Billboard Chart Beat Podcast, where each week co-hosts Gary Trust and Trevor Anderson, from the Billboard charts department, discuss why what's on the charts … is on the charts, while also looking at current chart action in a historical context for even greater insights.   

This week, we recap Ed Sheeran and Justin Bieber's arrival on the Billboard Hot 100 at No. 2 with "I Don't Care." In honor of the entrance, we look at Sheeran's sonic evolution, from folky first hits "The A Team" and "Lego House" to his newest music, with his just-announced new album, No.6 Collaborations Project (due July 12), finding him also collaborating with Chance the Rapper and PnB Rock, among others.

Gary, Trevor and Billboard.com senior editor Andrew Unterberger further delve into pop's past and consider other acts whose sounds changed significantly. Among them: The Beatles, who transitioned from early bubblegum to psychedelic rock; Bee Gees, who traded pop-folk for disco; Alanis Morissette, whose pop-dance origins are largely forgotten thanks to her Jagged Little Pill alt breakthrough; and, in more recent years, P!nk, Maroon 5, Katy Perry, Taylor Swift, Bruno Mars and more.
