Please help with 90's rap song

I found this song on tape, but it's medium quality and I would like to know who sing it. In the refrain girls/women sing "Round and round, the world will go, round and round nobody knows..." and something other. The verses are rap by the women I'm still learning english (I'm not Englishman/American, I'm Pole) so I don't sure if I good understand this words. There is the link to page, where the song is. I searched this on many ways but nothing help! If anybody could help me I would be really cheerful, thanks for any help!

the lyrics don't match exactly and it's no rap at all but i try it though:

En Vogue - Time Goes On

Thanks wurzlsepp, you are helpful, but this is not it. I sent a link to this song, and there it is. It's rap and the lyrics which I wrote is the beggining of this song. If you would know something more please write it. All in all thank you for your help
P.S. If there is not link just in case I send it again:
