Kendrick Lamar joins Imagine Dragons for 'Saturday Night Live' performance

Kendrick Lamar was a surprise guest during Imagine Dragons SNL set last night. K-Dot joined the group for a new version of "Radioactive", much in the same way he did during the Grammys. The performance was a victory on two fronts as it added a much needed punch to a song called "the worst song ever made" by some and gives Kendrick exposure to people who would have never heard of him otherwise (like the Grammy voters. ZING).

Lamar's Grammy snub prior to the crowd-silencing mashup is still causing heated debate a week after the ceremony aired. Macklemore publicly apologized for the win and prominent rappers have chosen sides.
