Unfortunately, I can't make out many of the lyrics other than "Baby, baby," which appears often throughout the song. But its a female singer, and towards the end of the song there are back-up singers singing a few lines very fast while the main singer hits a really high note. I really don't have any idea who it is, but I guess I'd say the main singer's voice reminds me of Mariah Carey.
I know it's vague, but most of the lyrics are said too fast for me to catch what they're saying. Any help would be appreciated.
