Update: Original source CITEworld has retracted their story -- "Due to writer error, an original version of this article stated that Iron Maiden used MusicMetric's analysis to plan its South American tours. MusicMetric did not work directly with Iron Maiden. The analysis described in this article was carried out without the band's participation or knowledge, and we have no confirmation that the band ever saw or used it. CITEworld deeply regrets this error, and we apologize to our readers."
Illegally downloading music is frowned upon, but Iron Maiden have managed to turn the issue into a positive. Instead of filing lawsuits or barraging the media with a list of names who have stolen music, Iron Maiden have instead used file-sharing information to plan their tour itineraries.
