This was the last song Audioslave wrote before they broke up in 2007. Revelations was originally complete with 11 songs, but producer Brendan O'Brien insisted he wanted a big, loud closer for the album. The next day, the band came up with "Moth."
The last lyrics Chris Cornell ever sang for Audioslave were, "I won't fly around your fire anymore," before he left the band to pursue his solo career.
Meghan Trainor and her producer Kevin Kadish originally wrote "All About That Bass" for another artist to record. However, after Epic Records boss LA Reid heard Meghan play a demo of the song on a ukulele, he signed the young songwriter to his label and told her she should sing it.
