"Been tryna hunt me down like a dog, cause you're on my as..." (Eminem – Asshole) | accepted

He paints a vivid picture here: a dog is chasing another one, attempting to reach the other’s rear end with his nose (get a scent) but Eminem’s in a rush, because he has already run out of time so no one can catch up with his pace.
ALso: you can’t get a ‘cent’ from his ‘spare’ time, because it’s already ‘spent’….

"Better pack toilet paper / But I'm taking no crap, ho, he..." (Eminem – Asshole) | rejected

Also, a better pack toilet paper contains a lot of rolls

"Or you better not come out" (Eminem – Asshole) | accepted

This also ring bells to me with the Spartan saying “With it or on it!"
[Spartan mothers or wives gave a departing warrior his shield with these words, implying that he should return (victoriously) with his shield, or (his dead body) upon it, but by no means after saving himself by throwing away his heavy shield and fleeing]

"Bad is to Evil, a roofie to Roethlisberger" (Bad Meets Evil – I'm on Everything) | pending

"Shawty cool as a fan, on the move once again" (Justin Timberlake – My Love) | pending

Agreed. It’s under a) in the explanation…

Mad props for RG for hiding the leaked songs' lyrics and supporting Art!!!

"Cause the very thing that I love's killing me and I can't..." (Eminem – The Monster) | rejected

tal, mee too, I thought he said “Own CD”

"[Intro]" (Eminem – Careful What You Wish For) | rejected

This intro always reminds me of T.I.’s *Act I: T.I.P. off his 2006 album T.I. vs. T.I.P. I think the similarity is so plain this is clearly a reference to that song.

"At least I know that I don't know" (Eminem – Berzerk) | accepted

In Plato’s Apology Socrates says it in essenc: “So I am better off than he is — for he knows nothing, and thinks that he knows. I neither know nor think that I know. In this latter particular, then, I seem to have slightly the advantage of him.”
