VEVO does a segment, apparently, called ":60 With" where they spend a minute with an artist and fire off a series of quick questions. Kendrick Lamar is the latest subject of their ":60 With" series, which you can watch above.
Among the brief question and answers, Kendrick chooses his favorite letter between "I" and "U"(he chooses "U"), he describes his "King Kunta" instrumental in three words ("aggressive, harsh, unapologetic"), which Tupac track he'd like to drop a verse on ("Ambitionz Of A Ridah") and the new track he's most excited to perform live ("Wesley's Theory").
