Busy Bee was top dog, #1 MC
Kool Moe Dee is an interesting guy and his backstory is worth reading up on...but he battled Busy Bee live in a club and basically ended dude's career
Busy Bee should've been what Kurtis Blow was
Being that KMD was now the man, he would be challenged
My understanding was BDK took issue with I Go To Work, being that he had released I Get The Job Done
i.e. he didn't appreciate how similar the 2 songs were (yes, this is all it took back then to get checked)
Alot of MCs felt some kind of way about How You Like Me Now
KMD also had a track out Let's Go, which is an LL diss
but BDK also took issue with the line...'make you say daddy I don't want none'
So he lifted it and used it for the chorus of my favorite battle record EVAH

I use to play mortal kombat on repeat

I learned all of this later though. When that album came out, that song was my jam.

There's a story out more recently, that BDK tried to use the same path as KMD, and had challenged KMD to a battle while he was still a teenager

KMD laughed it off

KMD's song Let's Go was actually directed at LL
LL responded with Momma Said Knock You Out

Anyway, you can see how saying somebody's name on a diss record wasn't a big deal

THEY KNOW

WE KNOW

EVERYBODY KNOWS who they are talking about

I don't think there's much to the beefs above personally, just KMD had that spot and the young guys came for it

There's a rich history of battling, live and on wax, in hip hop

Definitely worth looking into

It's kind of the way that MCs cut their teeth in the early days
