6 years is just toooooo long for a hiatus and by the time one comes back,almost everything in the industry has changed...Its only SADE & GARTH BROOKS who can go away for that long and still come back strong,coz their style is basically UNIQUE.Nelly should have come back in 2009 b4 TEENAGE DREAM (a mediocre and cheap version of loose) was released,the same applies to her friend Justin Timberlake *sidenote*how come bieber's song BOYFRIEND sounds like a horribly done version of timberlake's LIKE I LOVE YOU?
