It is, and she does. The sound of the song would fit right into one of Tina Arena's last two English albums. The song also scores for using the word "troublesome". If there's another song it's been used in I can't think of it. Interesting that there are a number of backing vocalists in the chorus. Particularly with the song title and the fact it's her first proper solo song. I'm getting a "bullied Twitter victim strikes back" vibe from the lyrics. Never a good colour on Claire. I've seen it in many. "M" standing for "Megamouth", of course.
