作曲 : Gary Cherone & Nuno Bettencourt
 作词 : Bettencourt, Cherone
 Everybody was born in it
 Sure as hell, gonna die in it
 Some people don't give a shit
 Whether or not, they're full of it
 It's on my mind
 Most of the time
 That's when you find
 We all go blind
 Then it will start
 to get in our hearts
 It's gone too far
 That's who we are
 It's a monster (We all have within us)
 It's a monster (It's a monster)
 It's a monster
 It's a monster (Turns us into sinners)
 It's a monster (It's a monster)
 It started when I played with it
 It turned into a habit
 And after that
 Once you've been bit
 You can't seem to get rid of it
 It's on my mind
 Most of the time
 That's when I find
 We all go blind
 Then it will start
 to get in our hearts
 It's gone too far
 That's who we are
 It's a monster (We all have within us)
 It's a monster (It's a monster)
 It's a monster
 It's a monster (Turns us into sinners)
 It's a monster (It's a monster)
 It's a monster (We all have within us)
 It's a monster (It's a monster)
 It's a monster
 It's a monster (Turns us into sinners)
 (repeat)
