It's Monday, the Holiday season is well and truly over, and despair may be the feeling of the day. Still, fear not, because YouTube has the answer to brighten your mood! No, it's not a sneezing panda, or a puppy doing the cutest things, or even a rubbish Gangnam Style routine. Oh no, it's music from Super Mario Bros. with a metal twist.

Courtesy of a talented guitarist and Youtube channel 331Erock, we have four minutes of remixed, awesome Mario music. This chap has some skills — or skillz, if you prefer — so we'll let the video do the rest.
