I know that what i am about to say is off-topic, but I had to respond to the first part of your comment...I mean, people go and see some DJ at a club. They use terms like "he's one of the best DJ's in the country". I mean...um...he spins records. How is that a musical talent?
What exactly does constitute musical talent? Is it holding a piece of wood in your hand that has six strings and plucking the strings? Or is it hitting keys on a piano? Or is it moving your hands closer to and further away from a theremin?
When broken down to its basics, all musical instruments seem ridiculously simple. However, as anyone who has ever picked up a guitar, or a bass, or sat at a pair of drums will know, actually creating something using those instruments is extremely difficult.
The same goes for dj'ing. Putting a record on a turntable is a task anyone with a brain can do. However, creating an hour long composition where music that should not go together flows seemlessly, due to the djs ability to beat match, scratch and countless other things, takes real skill. It is this skill that seperates good djs from the guy who called himself a dj at your bar mitzvah.
There is a ton of music out there if you wish to wet your whistle. If you want to hear kind of music a dj can make, I suggest you listen to one of or all of the following:
Mark Farina - Mushroom Jazz
DJ Shadow - Endtroducing
Amon Tobin - Bricolage
Jurassic 5 - Power in Numbers
Go see the movie Scratch.
