If you didn’t know that his heart was cold, well, now you know.
(F.Y.I = For Your Information)

Very similar to the famous Biggie line.

Also notice the technical nuances in this line:

If you break down the sounds and listen to his pronunciation, “If ya ain’t” carries the rhythm of “F.Y.I” until the “I”, which is replaced by “knowing”. Thus this serves as a great transition line for the next rhyme scheme, where “knowing” becomes the dominant rhyme:

It’s F.Y.I, if ya ain’t knowing
What, go with you? Where? Nah, ain’t going.
Oh wait, you wanna date? Oh, well in that case ho, it’s June 8th, oh! and
Kinda like Beethoven composin' a symphony of hate
So much hate woven into these raps

Bear in mind that a lot of the words highlighted don’t rhyme by themselves, but Em manipulates their sound to make them rhyme. This is a characteristic feature of Eminem, and he’s talked about it in this interview:

Nowadays hip-hop is seen as, as long as the song has a catchy hook and some sort of techno beat behind it, its good. Doesn’t matter who the artist is.

Here’s a solid example:

It isn’t about the song being “quality” or not, hip-hop fans are notoriously fickle; more-so than fans of other genres. A rapper who’s “hot” or has a buzz one year, can vanish the next year. You don’t see many successful rappers with longevity like a Jay-Z. ALSO rap fans often times complain when a rapper does the same thing over and over. People used to complain about Papoose being too one dimensional and couldn’t make a song for the radio. It doesn’t matter how good the music is, if it doesn’t fit what’s currently hot, it’s disregarded by the mainstream public.

They may never had the best grades, but they knew how to survive in the streets. Also they knew the stuff to keep ‘em makin’ music for all of us

Could be a reference to one of Classified’s older song called Unusual featuring Joe Budden.

Michael Bay is a very famous director who had directed films such as Armageddon, Pearl Harbor and the Transformers film series.

Just as Bay gave direction to those movies, Class gives himself direction by writing and spitting raps.

Hit ‘Em Up is a legendary beef song directed at The Notorious B.I.G by Tupac Shakur, as well as the track where the beat to this half of the song comes from.

This is Royce’s verse in Above The Law with Eminem as “Bad Meets Evil”.
