Mein Herz brennt (My Heart Burns) is the first track of the album Mutter.
Part of the lyrics come from an old children's television show in Germany. The lyrics talk about childhood nightmares. The song was frequently mistaken for a composition from Final Fantasy X, due to the dark tone of the orchestra and rock influence.
This song has been remixed with Rammstein and Russian pop duo t.A.T.u with the song "Я твоя не первая" or "Ya tvoya ne pervaya" (Translated to English as "I'm Not Your First") under the Russian name "Одно И То Же" or "Odno I To Zhe" (Translated to English as "One And The Same").
Part of this song is actually taken from a children's show called Das Sandmännchen (The Little Sandman). Every night the show would come on and the das Sandmännchen would tell bedtime stories. Each show started out with "Nun, liebe Kinder, gebt fein Acht. Ich habe euch etwas mitgebracht" ("Now, dear children, pay attention. I have brought something for you").
