Pretty much every genre of music relies on some kind of rhythm to set the pace. Hip Hip and Rap is no exception. To make a song that will be noticed by people a recording artist needs a hot instrumental with a catchy rhythm to write and record over.
Nowadays the rhyme structure and delivery of any given rapper can come in many different paces and rhythms, which is why finding the correct beat to work with is so important to the final track coming out right. Finding the right instrumental is literal the difference between greatness and being shelved by your very own fans ..
Writing your lyrics to fit the beat is often a very good idea. A good instrumental can spark a free flow of lyrical genius that should, in most cases, fit the track you are writing it too with very little modification. Letting the beat selection lead the way is a great idea for getting your juices juices flowing until the song concept and lyrics start to emerge.
However a large number of rappers practice what is called “dry writing” or writing without a beat. In this case all this is left to do is find the right beat to capture the essence of what's been written on the paper. To make sure that the song will be remembered for the way everything matched up so well that it looks like the lyrics are the only ones that will sound good on that beat, ever. Finding the instrumental to do that can be a challenge though.
The search begins with sites like soundclick, one of the largest online sources for hip hop instrumentals and beats.

A classic song is something that almost grants the artist immortality in a certain respect. Long after your dead you will still have a loyal fan base listening to your work, and honestly is not that what every artist is waiting for in the long run?
