From Other Experiments:
Screwed – original, I believe
Bills Bills Bills – cover
Laptop Like You – original, I believe
Bacteria – tricky to answer the question, but I’d say no – the words themselves are samples from a KFC training video
Brookline – original
DSJD – original
Beds Hurt My Booty – no, another sampled track
I Crush Everything – original
In fact, everything past this point is original, I’m pretty sure.
