There's a Minecraft Christmas song. It's by Area 11, a band from England. As of two days ago, it was apparently just outside the top 40 singles in the United Kingdom, given a massive boost by the popular Minecraft community program Yogscast.
Those fearing that video game communities can somehow and suddenly sabotage the record industry's machinations, don't worry. With that bump already done with, the song has slipped all the way out of the top 100.
