RnB: Anything is acceptable. There's a ton of GREAT RnB music out by females.
Rap: Way fewer options. Off the top of the head:
When your body hit the concrete, I couldn't help but scream
Blood fowing fluid, life is but a dream
'Til a bullet takes your last breath, where the angel slept
You were received comfortably and the heavens wept
Man you threw me for a loop, had me questioning exitstance
Like why I'm still living and do angels give kisses?
'Cause sometimes in the middle of the night
I can feel you by my side saying let's ride
So I hug myself a little stronger, bring the pain closer
Get mad at the world then once again regain composure
Closure, can't seem to find that these days
Seems like everywhere I look, another soldier's laid
My love you looked so peaceful wanted to give you two breaths
Pump five times on your chest to break the silence that you left
Instead I paid respects, caressed your cold face
Whispered you know I'll always love you with amazing grace
This was a pretty good album...
