  That is the song by Paulina Rubio that I've been obsessed with for 3 days now. Heard 5 seconds of it on a commercial on Vh1 and searched on Yahoo for the title. Paulina Rubio apparently sings it. Downloaded it from iTunes Music Store and now can't stop playing it. But I have to play it on my iPod 'cause roommates are sick of hearing me play it on repeat. AAAAHHHHHH
