gansta rap song from late 90s/ early 2000s?

i dnt remember any lyrics, but i think it was lik biggie, pac or nas or some one else like that. it starts wit like radio static and ppl talkin in the background and then a women is singing the chorus. i think it had a pretty heavy beat and a sample that went something like B flat, A, G, A (musical notes). hope thats enough if u recognize it at all plz tell me
