“I Be Scared” is the first new song in nearly a year from Knoxville’s Yung Life, a duo made up of Elliott White (ex-Coolrunnings) and Will Farner. Six words are all the lyrics require, repeated and reconfigured over a driving keyboard riff and surprise heavy guitar. If the song title’s awkward verb tense rubs the wrong way, take solace in the top Google searches for the phrase: Should I be scared to take ecstasy for the first time? Should I be scared of this wasp nest? The dentist? Starting high school? To have sex again?
