Pentatonix cover Cher's 'Believe' with impressive a cappella '90s dance medley

Three-time Grammy Award-winning group Pentatonix have just dropped one awesome medley of dance songs from the '90s - and we are loving it!

Putting their signature spin on a bunch of popular songs - including Jennifer Lopez's 'Waiting for Tonight,' Cher's 'Believe,' Haddaway's 'What Is Love' and Vengaboys' 'Boom Boom Boom Boom' - the quintet created an upbeat mashup while showing off their powerhouse vocals.

Kevin Olusola, Matt Sallee, Mitch Grassi, Scott Hoying, and Kirstin Maldonado took to social media to announce the new song, as well as their new album, The Lucky Ones.
