Finding an old R&B song?

Question

This song was also sampled in a rap song about 10 years ago or within. All I remember is the chorus. Here it is and the chorus has exactly that many oohs:

Oh hoo oh hoo oh hoo oh hoo

This is not In Falsetto or Southside by ashanti. Thank you.

LL Cool J - Aint Nobody????   Original by Chaka Khan
