trent reznor/NIN did a simular thing for people with his "with teeth" track, for people with apple's garage band software. and there are tonnes of people providing semi stripped down tracks for sonicfoundry's/sony's acid software.

sure the lines between dj'ing and performing your own material is becoming thinner and thinner these days (which is good because it allows people to be more creative and allowing them to shine through more than what new promo or white label they have) but it also be a double edged sword and allow the uncreative to be more lazy. but as always, true tallent shines.

but my question is that when you stop spinning discs (vinyl or cd's) can it still be called being a disc jockey? or would you just be a gear whore?

i personally believe that if you don't have to worry about playing with the pitch of a song/loop (ie, it's pre-done or calculated for you) then it's not dj'ing.
