Every rapper wants to be heard and one of the best ways to go about getting your voice heard is to get you music into the club by putting out songs over club beats. Some people seem to have reservations about this particular method of getting their music heard. I as if you're somehow selling your soul by putting your music over a club beat. The problems with this view are too many to recount hear. Suffice it to say that the type of beat you choose to rap to will never determine whether or not you're a sell out.
By rapping to a club beat you can actually get your foot in the door. Every Thursday, Friday and Saturday night people pack clubs all over the country. Clubs are constantly going through different DJs to get people into their establishments. Some of the DJs are well seasoned in the game and others are brand new just starting out, but both of them will accept music from unknown rappers as long as the flow is tight and the club beat is hot. The main factor which drives a DJ to play one song or another, in most clubs, is his feeling on whether or not the beat is going to get people moving and excited. Just think how many times you've been in the club and the music sucked and people stopped dancing, that's exactly the same moment when customers start to leave the club. Because of this, club owners will cycle through DJs until they find one that keeps people inside and buying drinks.
This fast turnover means there's always a long list of DJs out there looking for work and working over vast regions so they can bring in enough money to support themselves. Oftentimes a DJ will stick in one location once he's established himself there. But in both cases you get them to play your music. If you flow and the club beats are hot then he might consider taking you on. In other cases you can Google search for DJs in your area and approach them with your music. DJs who are actively looking for work might be more likely to pick up one of your songs, especially if you've got a good story.
While it is about how hot the club beat is and whether or not you've got any skills as a rapper, you had better figure out a story to tell about yourself so that you can get in the DJs good graces. And this is not to say that you've got to make anything up, you'd just better have your story straight is all. Tell him who you are and what you've done and say that you'd really like for him to play one of your songs. Make sure you can play your music for him on the spot without having to bother him with looking you up on Itunes or popping your antiquated disk into a CD player. You want to hit him fast and hard. Get your story out, and then show him you skills over the club beat.
