Ne-Yo's dance-pop hit "Closer" marked a musical departure for the singer-songwriter, who's known for a more soulful sound. The risk paid off. "Closer" topped the charts in the U.K. and was featured in episodes of Gossip Girl and 90210. "It was very much inspired by just the vibe of some of these house and techno clubs we went to while we were in London," Ne-Yo explained. "You know, kinda smoky, kinda dark and mysterious ... With just that constant, four-on-the-floor house beat … I basically tried to capture that energy and put the Ne-Yo spin on it. And 'Closer' was the end result."
