Even Mariah Carey in her prime had background singers - Kelly Price, Trey Lorenz etc. We all know it’s not because she couldn’t sing, it’s Mariah Carey! But like you said, it’s to add a different flavor and sound.

When a rapper features other rappers, it’s not because they can’t rap, it’s to add a different flow and dynamic to the track. It’s about meshing one style with another.
