Several artists have found that some of their studio work have been leaked onto the Internet before their album has been completed. System of a Down's 2002 follow-up to "Toxicity", untitled at the time, was leaked onto the Internet as MP3 files. When the album was released under the title "Steal This Album!" the songs were significantly different from the work-in-progress, with different titles, lyrics and even melodies. There were some reports that the changes were a direct result of negative feedback about the leaked material.
