In 2008, after trawling the net for weeks in search of decent Christian power metal, I decided to buy Frozen Inside by HB on iTunes.
Then I saw Mirror of Souls in the "Listeners Also Bought" list. The artwork looked good and a few seconds of samples sounded good, but I wasn't sure what to think of there being only 8 tracks, and one of them over 20 minutes. Really unsure, I made the purchase, and then worried that I'd made a mistake.
A couple of hours later, when I'd listened to Frozen Inside & Mirror of Souls, my mind was blown, and Theocracy has been my favourite band ever since!
I praise God for Theocracy, and I thank iTunes for the suggestion!!!
