Stop what you're doing ... put down the Cheetos ... and listen to the magic that is Ray J as he sings about banging Kim Kardashian ... 'cause TMZ has the first clip.
Ladies and gentleman ... we give you 30 seconds of "I Hit It First." You're welcome.
Now that you've listened -- and let's be honest it's pretty catchy -- remember why we've gathered here today ... so Ray J can remind Kanye West he's getting nothing but sloppy seconds.
Kanye WOULD respond with a rebuttal track ... but he's too busy releasing chart-topping albums.
