Speaking to SpazioRock.it
bassist and co-vocalist Troy Sanders responded to the comment that there are more memorable choruses on Once More 'Round The Sun
compared to some of Mastodon's previous albums. He said: "We've tried to incorporate more melody - not only guitar-wise, but vocal melodies and vocal harmonies and vocal patterns that really are catchy; you know, like, hooks that bring you in and make a song more memorable. So we did spend more time and effort on trying to find those right vocal moments for this new record without cheating the song's music itself."
Sanders continued: "You can find vocal patterns that are catchy and meaningful to the song without just being cheesy about it and singing for the sake of not screaming. We're always trying to be better songwriters, and just continue to evolve and make songs that don't sound like the last song we wrote."
