"Monster" was Skillet's breakthrough single in 2009, and is their most successful single to date! The song hit number 1 on Christian Rock Radio , number 20 on the Billboard Rock charts, and number 4 on the US Active Rock charts!
The song is about not wanting other people to see the bad side of you. Everybody has their flaws that they'd like to get rid of, but sometimes it's difficult to hide and it feels like a monster inside of you waiting to awaken.
