So the band used data from Musicmetric to see where its biggest fans were — including the biggest pirates of its music. Turns out, some of the biggest fans live in South America, so Maiden booked a bunch of tours there, and made millions. The results helped Iron Maiden LLC become one of six music firms in the UK to outperform the music sector as a whole. Plus, made a lot of heshers happy.
