There is a so-called remix of R. Kelly's song "Ignition": "Ignition (Remix)", which is actually a song in its own right and was more successful than the original song. Interestingly, the supposed remix was also written around five years earlier than the original. "Ignition (Remix)" was a massive hit. In the USA, it reached number 2 on the Billboard Hot 100 and was the second most successful single of the year in 2003 according to the Billboard Year-End Chart. Internationally, it topped the charts in the UK, Australia, New Zealand and Ireland.
The German rap group K.I.Z. took this supposed remix version and made a humorous German version of it, which became an underground hit in Berlin. But you have to listen to it to the end to find out.
There is an unreleased earlier version of the song, which is said to circulate under "Was willst du tun?" and contains a different outro.
