Not only that.. the best bit about DJ'ing isn't the actual mixing. It's the digging to find new sounds and artists that you want/need to have in your collection. Of course if you know what you like and the kind of thing you after then people can provide artists they think you can check out but for the most part it should be down to the individual to seek out the sounds. That is after all why anyone would want to start DJ'ing surely... for the love of the music?
