You know how there are some songs you have to hear a million times before they stick but then others are total ear worms within the first 30 seconds of listening? The latter is every Shawn Mendes song. Ever. What is it about Shawn Mendes that makes his tunes completely addicting? Between his easy-to-listen-to voice and his beyond-catchy hooks, it is no surprise that this young (he’s only 18!) Canadian pop star is a chart-topper. Current S.M. favorite: ‘There’s Nothin’ Holding Me Back’. Dance along to Zumba® Jammer Diego Chauca‘s choreography set to the hit single and take it to a Zumba® class near you. There’s nothing stopping you.
