Career-wise, Mariah Carey is almost as powerful as she's ever been: She's established enough that people are going to buy her music, even if her first single is a response to an Eminem insult and it's 2009; She has her own perfume line that people actually buy (apparently some people want to smell like an 8-octave range and Sanrio); I'm pretty sure she owns the rights to all the butterfly images in North America; And she's getting good reviews for her light-mustache acting in Precious.
Basically, Mariah Carey can do whatever she wants. And now, almost as if to prove it, she's released a video for a cover of Foriegner's "I Wanna Know What Love Is" that is so corny it's almost magical. Really, it's breathtaking. There are moments in the following video where children look at their parents, where friends look at friends, where a random patient looks at her orderly/possible lover, and they scream with their eyes, "Holy shit! Can this really be happening?" But it is happening, because Mariah made it happen.
