In case you were on Mars at the time, Kendrick Lamar stole the Grammy Awards broadcast with his performance during Imagine Dragons’ presentation of its top-selling song Radioactive.  And, oops, he (they) did it again on Saturday Night Live. Watch below (with far better sound than at the Grammys). Speaking of imagining, can you imagine how sick Imagine Dragons are of performing this simplistic song and banging those gongs?  The mind boggles and melts, radioactivity or not.
