MercyMe have achieved success with so many different styles that it's easy to forget their roots in alt-rock. Mid-'00s standouts “So Long Self,” with its trippy choruses and punky chords, and “Bless Me Indeed (Jabez's Song)” both utilize grungy fuzz, marrying CCM's inspired messages with an alternative edge. And even though 2014's “Shake” embraces dance-pop fun and soulful horns, the song is powered by a beefy modern-rock backbeat.
