As Justin Timberlake’s new solo album, “The 20/20 Experience” prepares to land in stores March 19, we take a look back at his best singles over the course of his career, whether as a solo artist, a member of ‘N Sync or as a featured artist.  These are based on our preference, not the song's chart rank. Regardless of whether you agree with our selections, there’s no denying that Timberlake brings something special to every song to which he lends his glorious falsetto and undeniable style...even if he isn't wearing a suit and tie.
