If you have watched any Vlogs on YouTube, then I would bet that you have heard music by Andrew Applepie.
He first got some notoriety in the United States when Casey Neistat started putting some of his music in his own vlogs. People liked his music so much, I think his reach just started growing. (I even emailed him and got permission to use his music in my own vlogs)
I am going to try and write a bit more about this creative musician but for now enjoy his music.
