These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: MF DOOM
Actually an MF Doombot: True to his inspiration, Doom has in fact sent impersonators to perform as "MF Doom" at his shows. This has not only angered many fans, but it has proven problematic when other artists such as Mos Def have pulled out of tours with him for fear that Doom might pull this trope.
Continuity Lockout: While it isn't super-hard to get caught up, some aspects of DOOM's work rely on the listener knowing a bit about his backstory and other work, and the fact that he does not always release his work under the MF DOOM/DOOM moniker.
One notable example is "Viktor Vaughn" on "Fancy Clown" off Madvillainy - the song becomes a lot funnier when you know that it is DOOM in his Viktor Vaughn rapping to himself on the track, but many first-time listeners may not be aware, as Madvillainy was one of his breakthrough works.
