At least they're trying. That's great.
Seriously. Nerd rock is cool because it's rough and melodic, and adapts well to 8-bit tributes. Nerd rap is just... dumb.
Some pasty white kid up there badly feigning a ghetto accent, rapping about his pampered, uninteresting life with an occasional "HAY GUYZ I PLAY VIDEOGAMES" reference thrown in. Once his act is over, it's time for the next pasty white kid to come up and do the same goddamn thing. Truth is, videogames of the era for which we are nostalgic were generally the purview of the upper middle class, a class that is not well known for its artistic contribution to rap or the rap culture. I'm not sure about the rest of you, but to me it's just embarassing and uncomfortable to watch.
