This deceptively simple little song is the musical equivalent of “kill ’em with kindness,” because even the most hate-fueled online troll couldn’t help but grin at the idea of Nashville singer/songwriter Corook—with an assist from musician girlfriend Olivia Barton—as a first-prize fish, the skippiest rock, or the happiest sock. With its strummy backdrop and kazoo interludes, “If I Were a Fish” would fit right in on a kids album, but its sweet core message (“How lucky are we of all the fish in the sea/ You get to be you and I get to be me?”) sounds like a lesson all ages could use.
