5 Christmas Songs, 10 genres.
Those christmas songs:
We Wish You a Merry Christmas (Traditional song with unknown origins, circa 1500)
We Three Kings (written in 1857 – John H. Hopkins, Jr.)
Jingle Bells (written in 1857 – James Pierpoint)
Silent Night (written in 1818 – Joseph Mohr)
12 Days of Christmas (Traditional song with unknown origins, circa 1780)
So those genres:
Christmas Dubstep (I imagine you guessed that one)
Christmas Electro House
Christmas Electro Pop
Christmas Chiptune (3 seconds, but still counts!)
…Funny how sticking “Christmas” in front of something makes a new genre.
