The real deejays are people who play music from media at radio stations and live events without scratching and mixing.
No necessary, the skills is another subject, someone can use a microphone between the tracks like the oldschool deejays, someone can make a perfect transition from one record to another, someone can scratch over a certain genre of music (hip-hop for example). This is all depends on the artist aka deejay. There is a big difference between a radio deejays and club deejays. Club deejay should move the crowd and unless the cowd like what he's doing and dance to it everything is ok, this is why the clubs book a deejays and pay them for what they are doing. Everyone can find the right club with the right music/sound and good deejays. Most of the commertial clubs are awful, but there are clubs for music lovers opened by music lovers (most of them are pretty small). This is how it works.
They aren’t really interested in sound quality as much as getting the music out to the listeners, so in that they are similar.
They are all different, but i'm sure everyone would love to play on perfect sound system, the problem is that the responsibility of the sound system belongs to the club/venue. I have linked some amazing venues with Audiophile Grade sound system in my previous post addressed to you. In the venues like that everything is just like at Audiohile's home, but this is a puplic venues for people who appreciate good mucis and top quality sound.
Part of the sub-culture of rap-“dj”s is about modifying the original sound, and while they use SL-1200mk2 turntables most often, they aren’t being used to transcribe anything but time code discs to drive serato-based systems to play out highly compressed semi-original content.
This is interesting, because the Digital vs. Analog debate is hot not only on audiophiles forum, but also in deejay community. In my opinion digital is a degradation of the art of deejaying. The main part of the DJ culture is crate digging. Deejays discover music, they are looking for vintage records, unknown tracks, they select music by mood, they are actually spend $$$$ on record every month! If they are good in what they are doing, but their fee per hour is high. This is a hard job.
Then we have digital devices like Serato. In my opinion a deejay should play real vinyl only. But i know serious vinyl collectors (djs) who can't travel abroad with 200-300 LPs, especially if you're on tour for a long time in different countries you can't bring all your records with you in a luggage (you can even lost your luggage after all), so they use their own digital copies from the original vinyl. I can understand that, but this is just usability. For a normal dj gig in their own town everyone can bring a box of vinyl, no problem.
The whole degradation of DJing began when amateurs became DJs (digital only) in the bars, they do not buy music, they do not have records, some of them are popular for another reason (designers, bloggers whatever). They do not ask for a high fee (and the bar owners are happy about it), some of them have very bad taste in music and their "performance" is just a bunch of random tunes in different genres played from mp3 or whatever they can download for free. They don't care about quality at all, all they need is some attention, free drinks and fun. Some of them can play with Serato, Pioneer CDJ players with flash card (with automatic mix option), but most of them playin with iPhone.
P.S. Everyone who's buying records is much more accurate in choice of music, because nice records are not cheap, you can not buy everything, no time and money for bad music. But digital crap can be downloaded for FREE in whatever format in gigabytes of files, or can be streamed for free anytime. As i said before Digital has no value.
Vinyl is a culture, Digital is just everyday life.
