“Titanium,” the song by David Guetta featuring Sia, is a hit, but imagine if it was done entirely by the human voice. A man who goes by AaronicStuff has been doing this for a while now as a hobby in his spare time. I first saw one of his videos about a year ago, and every time that I see a new one I’m simply blown away.

In his cover of “Titanium,” he’s accompanied by a female companion who sings both melody and harmony. He records the parts of the song and then splices them all together to make this end result, which is amazing. I can only imagine the effort that goes into one of his videos, and if YouTube ever hosts an awards show, this guy needs to be in the running.
