AVICII

Avicii's mixing skills have made him the most famous young Swede of the moment. He released his first album, True, in 2013, and is was a big hit. Fans are still dancing to it, although Avicii released two new singles recently, The Days and The Nights. And his new album, called Stories, is coming out soon. More of Avicii's mixing magic!

MARK RONSON

Mark Ronson's funk album, Uptown Special is a big success. It's the English musician's fourth studio album, but it's his first one to be a number one. Mark worked with someone famous on the album- Hawaiian singer Bruno Mars! Mars sang guest vocals on the single, "Uptown Funk". The duo produced a cool pop song and video (with a clear Michael Jackson influence) that makes you want to dance!

MADONNA

33 years after her debut single, Madonna has released her 13 album, Rebel Heart. Both Avicii and Kanye West worked on it. There's a gospel choir, piano, guitar and reggae too! The songs have religious references, and the album cover is designed to shock. Madonna hasn't changed at all!
