His names speaks for itself, must I elaborate why?
I will eventually start displaying 9 other songs of his best rhyming. The songs will be from his huge and prolific discography, perhaps one song from each album

A. "Calm Down"
The rhyme scheme I colored, which made all Em stans cry in anal agony, for actually showing in this thread, how his rhyming is above Em's level. I said I would complete the full version of his verse, it took me awhile but here it is. Busta's hook (with adlibs provided by the producer Scoop DeVille), setup's almost half of the rhyme scheme's structure
The opening quatrain seems simple, until it morphs into some giant beast, with an assortment of rhyming mastery that made even Em step his game up, Busta has said himself to which Mathers responded "I need to match your energy on this track", before mixing in his verse from his production studio

A1. The hook
A2. Here is 1/3 of his verse
A3. This is 2/3 of his verse
A4. This is the last 3/3
A5. The entire verse when put together OR to see it enlarged for viewing

Em's feature verse:
A6. The 1/2 of his verse
A7. The 2/2 of his verse
A8. The entire verse, when put together See it enlarged, below

Details: It's 58 bars due to Busta's mastery of enjambment (an East Coast rhyming technique) compresses the total from 64 to 58, with the technical effect in place. He used the enjambment ("dashes") for 24 lines, in TANDEM with his double-time, bringing it to 54 bars, which means he had 6 bars remaining where he spit normally. Though Busta's double-time was going awol for 30 extra bars (Busta's total is 60, if you remove Busta's enjambment for 12 bars (2 bars total with the dashed, combining "broken" pieces), and the other 12 (another 2 bars total, etc.) bars that used enjambment without a "speed boost" from doubling the tempo). Therefore it brings the sum of 64, to a 60 bar verse

Em who can't handle losing, also had a few tricks up his sleeve for the following reasons. He's from the Midwest, but this is rare instance of him using a technique associated with another regional scene in Hip-Hop (Such as Em matching Busta's technicality, by enjambment in a "restless" manner for 6 bars. Having no rests in Rap verse, is a signature of Midwest emcees).. So they literally went EXACTLY bar-for-bar, though Busta had the slight advantage. This is probably one of Rap's all-time most amazing collaborative showcases of emceeing from 2 Battle Rap legends, showing how they can have fun and outspit anyone as if they were still in their prime

B. Will be his entire song from "Gimme Some More"

C. His classic, breakout hit as a solo artist "Put Your Hands Where My Eyes Can See"

C2. Verse 1
C3. Hook
C4. Verse 2


E. "Pass The Courveisier Pt. 2"

F. "Arab Money"
