Stopheles - 2009-01-15 Fiving even though I'm not sure Myrmidon is using "seminal" correctly.

Myrmidon - 2009-01-15 Nearly screwed it up, since the first definition is about semen. But I think T.R.O.Y. counts as "highly original and influencing the development of future events" as far as Hip-Hop goes (assuming you ignore everything Puff Daddy did).
