Not as much as a strike as a claim, to be specific, requiring that he be the credited one.
Here's the problematic part and a potential resolution now, that I've listened to the song sample on Amazon.
He can claim that "Outro" is only derivative after what he's done with it. Which means leaning towards the Donna Burke-in-Eminem sampling. But it would not have allowed him to maintain that claim on the original Megalith track.
So I amend the plan of attack. Point of clarification to Spotify to check what copyright information is tagged onto "Outro", and if "Megalith" is credited. If it is, no longer a fuckboi, but someone tell YouTube that to clarify lest ad revenue is still going to the wrong pocket. If he did not note the use, sampling, or mixing of "Megalith", even if it was only for a bit, then fuckboi it is, and back to the original plan. It should be notable that the copyright information on the Amazon page for the "Outro" track does not credit anyone in the Namco sound team, Namco Bandai, or (I guess King Records?) for the use of "Megalith". https://www.amazon.com/Outro-Explicit/dp/B00AYBY902
It could be YouTube just fucking up, but that had to be some stupid AI to tag "Megalith" as the wrong song. ^(And besides, I've seen better remixes.)
I mean they just did a re-issues of all their albums on vinyl, you can buy the 2LP edition on amazon right now: https://www.amazon.com/Strictly-Business-Explicit-Epmd/dp/B00380DIUS/ref=sr_1_1?crid=1JQP9S54VWNX&keywords=epmd+strictly+business&qid=1550252759&s=gateway&sprefix=epmd+stric%2Caps%2C169&sr=8-1 . It sound fantastic.
