Its called PCDJ's music, Basically people who get songs and mix's them by using acapellas, and either using software on the pc to make there songs or using CD Decks. I was a PCDJ but im semi retired now.
My favorite music crosses many genres and artists, so long as it's good. While I don't really have a "favorite," I will say that Coldplay has more tracks in my Music Library than anyone else (particularly their recent Viva la Vida/Prospekt's March albums).
Although as I continue to age, I get more and more strange looks from those who seem to be getting younger and younger, I'm still into Rock. Here's one that's banging around inside my head on any given day lately.
If you a computer user and you know a bit about them you will probably like this http://uk.youtube.com/watch?v=SN1qVWpO-t8 I used this song plenty of times when i was PCDJ so you might have heard it, Its been out for a while. But i think its cool.
