2015 has been a big year for Justin Bieber. Instead of making headlines for egging antics or arrests, the 21-year-old pop star is grabbing attention for something else -- his music. His Skrillex/Diplo collaboration "Where Are U Now" is arguably the year's most original hit, and his lead single "What Do You Mean?" became his first Hot 100 No. 1.
