This is the title track of German pop rock band Tokio Hotel's third German and second English studio album.
On this song singer Bill Kaulitz shifts melodies a number of times over a backing of revved-up guitars. He told Rolling Stone: "At the end of this track we got rid of all the normal song structures. 'Humanoid' has so many different parts and melodies, it's a weird journey that might be a little confusing at the beginning, but we can't wait to play it live."
In an interview for iTunes, Kaulitz explained that the band came up with the album title prior to the writing of this song. He explained: "We had the album name first, but it didn't take long before the song "humanoid'' was there" Kaulitz added: "Humanoid is like a feeling about life that we have. The song is a bit like history, it takes you to a whole different universe. It's not a typical song, we let go of all the typical song structures, and there are a lot of different feelings and melodies in it, it became a whole different song, and that's what Humanoid is to us."
Producer/songwriter David Jost told MTV News that Kaulitz came up with the album title, Humanoid. He explained: "The word 'Humanoid' comes from the science-fiction language, meaning 'humanlike.' This word is pronounced differently in the English and German language but is written the same way in both languages. Bill wanted the new record to have only one name worldwide: Humanoid."
Tokio Hotel recorded both German and English versions of Humanoid. Kaulitz discussed with MTV News having to sing in German and English. "They have to do this super-complicated thing: change the session from German to English," he explained. "Yes, constant switches. I believe no other singer has to remember so many different lyrics like I do. It's only the third album, and I already have 10,000 songs."
