Monday February 23 marked the start of Season 8 of the U.S. version of The Voice, with a new round of Blind Auditions and the return of coach Christina Aguilera after two season off. It's too soon yet to guess who will follow in the footsteps of Season 7 winner Craig Wayne Boyd, but as we prepare to discover the next big talent, let's brush up on the incredible vocalists who've won the NBC singing competition up 'til now. To refresh your memory, here's a comprehensive list of past winners.

Season 1 Winner: Javier Colon (Coach: Adam Levine)

Season 2 Winner: Jermaine Paul (Coach: Blake Shelton)

Season 3 Winner: Cassadee Pope (Coach: Blake)

Season 4 Winner: Danielle Bradbery (Coach: Blake)

Season 5 Winner: Tessanne Chin (Coach: Adam)

Season 6 Winner: Josh Kaufman (Coach: Usher)

Season 7 Winner: Craig Wayne Boyd (Coach: Blake)

At this point, it may be more difficult to keep track of which coaches are staying and which are going. As mentioned above, Christina is back, while last season's newbie, Pharrell Williams is back for more. And, as always, Adam and Blake are ready to beat each other with in an inch of their lives to get the best talent on their teams.
