Oh people so Ive been looking for this song I guess from the 90's considering the whole vibe.
It's a hiphop RnB song and there's this really catchy whistle tune in it, then the verses are rapped and every 8 beats a guy in the background says "get up". And there's a part where he repeats a lot of something like "all I wanna do is wrong (get up)". Then at the end of the verse the guy ends with "...cause ba-by-here-I-am." and some girls/choir repeat "here I am!" And then the catchy whistle is back as chorus.
