Sick rap by Papoose, where he single-handedly goes through the letters of the alphabet rhyming words that begin with that same letter from A-Z.
Here is the first letter of Alphabetical Slaughter -

Alert assassins at large allegedly automatic artillery angrily aimed
and aggressively
Accurate AK's able doorways adversary afraid as active ammunition
abraise
And accumulated an alias after arrested
And accompanied armed accessories as an adolescent
