"Demons in You" is the second single by Finnish rock singer Tarja taken from her fourth studio album The Shadow Self.

The aggressive sound of the song comes from the need for Tarja to insert an extremely energetic track in her album.

The text of the song tells of the demons and the darkness that lie within people.

The album version features Alissa White-Gluz, the Arch Enemy frontwoman who sings in both growling and clean voice, and Chad Smith, the Red Hot Chili Peppers drummer.

The single also contains two additional versions of the song, one sung by only Tarja and the other featuring Alissa White-Gluz on lead vocal parts.
