Weekend radios have awesome DJ mixes, do they use PC's, dual CD players or something else?

I'm wanting to have an awesome new years eve bash with my friends, and I'd like to know how I would be able to do this with CD's or MP3's. I won't have a PC and I won't have time to find the instrumental versions of the songs, as well as vocals without the music.

Is there a frequency they use that cuts off vocals or what? This has always puzzled me, and now that I want to throw a party of my own, I want it to be as professional as possible, without hiring someone. Cuz, I wanna do it myself, it's more fun that way. =D

Ok, appearantly I need to make myself more clear. The stations that I listen to, when they do this sort of thing on the weekend, they have a live DJ there. He mixes the songs as they play, and usually does an intro that combines the song that was playing, and the song that's coming next.

How would I be able to do that live at my New Year's Eve bash? What equipment do I need?

radio stations usually pick up a programming service on remixes and usually those companies get special mixes from the record companies

Program Directors, or the people who choose what goes on the air, get promotional CD's from music companies, labels, and independent artists. The Program Directors listen to the music and if they like it, it goes on the air.

How they create the sound, well, I don't know. I know at least some use a program called Adobe Audition. We also use it at our station. I've heard you can strip the vocals from music but it's pretty hard and I'm not sure Adobe does it. Your best bet is to get downloading non-vocal versions of your songs!!

Usually, that kind of stuff is done in advance of the show and simply played over the air if the DJ does it him/herself. A lot of times, those kinds of mixes are versions of the songs the artists put out just to radio stations. If you do something like that, it'd probably be easier to prepare in advance.

i know what you're talking about. the answer is this: if it is a bigtime commercial station, then the mixes are made in advance of airing. they are likely to be made by a local club DJ - who will lay it down on one of his or her less busy nights - used to be to mini disc, but now also to a portable/hot swappable HDD.

then, one of the djs at the station, who likely has a better voice, will listen to it, and mark down drop points... when they can cut in and sound intelligent.

there are programs that will allow you to take songs and mix them like a club DJ. i knew a person who had this on his macbook and it worked great. i forget the name of the program. so i'm putting some generic links below for you to try. but if you want my advice: buy the program 'replay radio' and then capture the stream of a good station like soma fm... and use the mp3 magic or other editing program to take out their drops and insert your own.
