Nerdcore

Nerdcore hip hop, or geeksta rap, is a subgenre of hip hop music that is performed by nerds or geeks, and is characterized by themes and subject matter considered to be of general interest to nerds. Nerdcore has no unifying musical manifesto, and the sound of nerdcore varies wildly from artist to artist. One common theme, especially in the early days of the genre, is uncleared sampling.
