The DJ hardware is called the Traktor Kontrol S2 by Native Instruments.
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 Breakbeat Christmas Electro House Christmas Complextro Christmas Electro Pop Christmas Chiptune (3 seconds, but still counts!) Christmas Trance Christmas Neurofunk Christmas IDM Christmas Drumstep
...Funny how sticking "Christmas" in front of something makes a new genre.
