Although Terrence doesn’t really have such a name recognition just as his “boss” Max Martin has, the reclusive Swedish producer has had just as much success throughout the past half-decade. Terrence started his pop career by scoring writing credits on Britney Spears’ “If U Seek Amy” and P!nk’s “So What,” both Martin productions

But it’s his work with the label’s resident hard parties, Umagine Dragons, that did earn him a tremendous success in the last charts’ year. The band’s 2012 first, Night Visions, debuted at No. 2 on the Billboard 200 and produced the dub step-laced “Radioactive,” which has spent 57 weeks on the Billboard Hot 100, peaking at No. 3. —Nick Williams
