《Psycho》是Red Velvet演唱的歌曲，歌詞如下：
(Sic) You can call me a psycho (Sic)
(Sic) I'm a dangerous girl (Sic)
(Sic) You can call me a psycho (Sic)
(Sic) I'm a dangerous girl to play with
(Ver) You say you know my name
But you don't know my game
You say you're a gentleman
But you don't know my plan
(Ch) You can call me a psycho (Sic)
(Sic) But I'm the one to be with you (Sic)
You can call me a monster (Sic)
(Sic) But I'm the one you want (Sic)
You say you love me, but you don't show your face
You play with fire, but you don't feel the pain
(Ver) I'm a realist
So don't try to catch me in your dreams
I'm not your doll, so don't stick a label on me
I won't play your game, I won't lose my name (name)
(Rapper) If you play with fire, you must feel the pain (Oh~)
The world is spinning, the stars are bright (Oh~)
If you play with fire, you must feel the pain (Oh~)
I'm a dangerous girl, so stay away from me (Ah~)
(Ch) You can call me a psycho (Sic)
(Sic) But I'm the one to be with you (Sic)
You can call me a monster (Sic)
(Sic) But I'm the one you want (Sic)
You say you love me, but you don't show your face (Oh~)
You play with fire, but you don't feel the pain (Oh~)
(Bridge) So I play with fire with my heart and soul (Oh~)
And I play with fire with my dreams and desires (Oh~)
I won't let you break my heart and break my soul (Oh~)
I won't let you play with fire and burn me down (Oh~)
(Ver) If you want me, then come and get me (Yeah~)
But if you play with fire, then stay away from me (Oh~)
