It's like a Weird Al mad libs lyric, where the rapper tries to rhyme whatever techish things pop into mind. Sometimes it works. Sometimes it doesn't. MC Hawking is a great example. His track essentially an MC Battle style rap that relies on the synthesizer voice gimmick. But damnit it actually works. The lyrics are tight and amusing. I wish the hook was stronger, but thats a track I'll enjoy listening to. [...]
[A]t the end of the day, sometimes you just need to find a bit of music that you can relate to. And when you hear 'join me in the basement cuz it's warcraft patch day / time for D&D a frontalittle mainstay' day, so it's time to play D&D.... well, thats my Tuesday too.
Be sure to check out some of the artists listed on Wikipedia, for example, Commodore 64.
Formed by four members of a math club and breakdancing troupe in 1982 at a concert in New Jersey, Commodore 64 were the first group to release a single produced entirely using an Apple Macintosh computer, "Horton Hears A Ho" in 1999.
The MC Hawking entry includes sample lyrics ("I explode like a bomb. No one is spared. My power is my mass times the speed of light squared." - From "E = MC Hawking") and a fictional discography from the official website. Awesome.
