That definition would include both my 4 yr old daughter with a toy, and the teenager with his car stereo blasting across the beach.
I think you have to define "DJ" as either something marketable, or a technical skill set not possessed by others.
To get labelled as a Disc Jockey - you either have a tangible entertainment service or a marketable skill set. Without one or the other you're just one more person with a record collection.
Let me play devil's advocate here for a moment
Even if I expanded on my definition of a DJ and said: "The most basic definition of a DJ is someone whom plays a continuous stream of music for others to enjoy." The skillset required for the job is still very small. However I do agree, talent is needed in this profession.
Technically, a DJ doesn't need to be able to wire and troubleshoot his own system, in any other AV field that job would be done by an engineer. A DJ doesn't have to market himself as that would be done by a PR firm. A DJ doesn't need to keep his books as that would be done by a bookkeeper. We don't have to do all these but it behooves us to as it keeps operating expenses down considerably. If we were to hire out each of the jobs that your typical DJ does himself we'd probably be running in the red with nearly every show.
Of course, I realize we're talking about two different things here.. You're talking about an owner/operator who happens to be a DJ. I'm talking about strictly being a DJ. I could switch DJ with any other small business owner/operater and make the same argument I suppose.
I guess I don't quite know where the line got so blurred that many of us, even industry veterans, cannot step back and agree on a basic definition of "DJ".
Video montages and interactive games aren't in any way shape or form part of DJing yet many are up selling these services at a nice profit. For those that do upsell great for them however these thing are still not in the realm of strictly DJing.. You're better off calling yourself an entertainer rather than a DJ.
