Title: "Cry me a River"
Artist: Justin TimberlakeDetails: Before he put on his suit and tie, before he brought sexy back, Justin Timberlake was just an ex-boyband frontman with curly hair and a beautiful falsetto. When he finally went solo and released "Justified," hits like "Cry Me a River" changed how the world thought of JT from N*SYNC.
These days: What isn't Justin doing these days? He's still coming out with hits like this summer's "Mirrors," guest starring on SNL whenever the mood strikes him, hanging out with Jay-Z, and generally being an all-out boss.
