User blog comment:Bobdave/Epic Rap Battles: Modern vs Classic. Alex Trebek vs Nostradamus/@comment-29125272-20161030125052/@comment-4490782-20161030224143

The difference with Pac vs Chainz is that rap's around 40 years old so that's a fair chunk. Specifically with the more modern style of rap being far more recent. The gap is comparably big, although its semi-closeness is part of the reason I think it's more off-season material. Stronk men have been around far longer.

Also famous stronk men is not a particularly fun battle idea imo.
