    The award-winning international phenomenon THE X FACTOR is back. In Season Three of the hit competition series hosted by Mario Lopez, THE X FACTOR judges will travel the nation searching for talent 12 years old or over -- both solo artists and vocal groups -- who are willing to brave the panel for a chance to make their dreams of becoming a superstar come true. Auditions for THE X FACTOR were held this spring in Los Angeles, CA; Charleston, SC; New Orleans, LA; Long Island, NY; and Denver, CO.
    Contestants will audition in front of THE X FACTOR judges, including Simon Cowell, Demi Lovato, Kelly Rowland, Paulina Rubio, and an audience of thousands. This will be the ultimate test to prove they have the vocal ability, charisma and stage presence it takes to become a global superstar or breakout music act and win a recording contract with Syco/Sony Music.
    Those contestants who survive the first auditions will be divided into four categories: Boys, Girls, Over 25s and Groups. Each category will be mentored by one of the show's judges. Not only is it a competition between the hopefuls to stake their claim for the coveted win, but it's also a showdown among the judges as to whose acts will dominate the competition and make it to the finals. The judges may have their say in how the competition progresses, but it will be up to America to decide who ultimately has THE X FACTOR.

    Baby, can't you see, I'm calling
    A guy like you
    Should wear a warning
    It's dangerous, I'm fallin'
    There's no escape
    I can't wait
    I need a hit
    Baby, give me it
    It's dangerous, I'm lovin' it
    Too high, can't come down
    Losing my head, it's spinning 'round and 'round
    Do you feel me now
    Taste of your lips, I'm on a ride
    You're toxic I'm slipping under
    With a taste of a poison paradise
    I'm addicted to you
    Don't you know that you're toxic
    Don't you love what you do
    Don't you know that you're toxic
    It's getting late to give you up
    I took a sip from my devil's cup
    Slowly, it's taking over me
    Too high, can't come down
    It's in the air, it's all around
    Can you feel me now
    Taste of your lips, I'm on a ride
    You're toxic I'm slipping under
    With a taste of a poison paradise
    I'm addicted to you
    Don't you know that you're toxic
    Don't you love what you do
    Don't you know that you're toxic
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now
    Intoxicate me now, with your lovin' now
    I think I'm ready now, I think I'm ready now

    This style for the song sounds veeeery familiar. Hm. Reminds back in 2012 on the Voice when Melanie Martinez was singing this exact song in this exact style and this episode took place in 2013.

    Too bad she turned into a gold-digging ho and ditched him for more money.
    Then she goes and gets a bunch of plastic surgery done and is now your typical Hollywood slag.
    She looked so nice here too, and her quirky vibe worked.
