Curren$y Spitta type beat
It may seem it's obvious but with no good rap beats, there is a constant go far inside the hip hop game. Lyrics are crucial, yes, but I would reason that the beat is equally as important, or even more. A fantastic rap beat is very important. Without it, you should just sing freestyle.
Curren$y Spitta type instrumental
Here is a great example: Think of a great lyrical rapper. Say Eminem. Now, picture him rapping broke but a blender in private. It would suck, no? OK, it's perfectly possibly Eminem could achieve it but you get a picture. Now consider Eminem rapping with a terrible instrumental. It might sound a bit better, nevertheless, you would not get this full impact with the song. He probably wouldn't sell many albums, would he?
The fact of the matter is: Eminem is well known because he's an incredible rapper, but half the credit would travel to Dr. Dre for creating some sick beats. What i'm saying is, if you listen to a number of Dr. Dre's beats, it is not easy to see how any rapper can produce a bad song. The beat plus the lyrics work together to generate a perfect song.
Thus regardless if you are rapping about the story you have ever had, and you need a powerful instrumental to improve it, or perhaps you only need some clever metaphors as well as have the song blasting in peoples' cars, your song is dependent upon good rap beats.
Another topic I choose to mention: deciding on the right instrumental what you're rapping about. For example, Immortal Technique uses guitar/piano type beats, funky type old fashioned beats, and are generally suited to exactly what he raps about, because they are a lot more of a serious rapper. You wouldn't hear him performing "You Never Know" using the beat "Laffy Taffy" (If you haven't heard That knows, take off tune in to it).
You must find your style of beat. Just one more example: you most likely wouldn't hear NWA rapping into a Dirty South crunk beat. Not merely basically because they aren't still making songs, speculate it would go against their style.
With a good rap beat, you may be something special. If you got the guts along with a dream, you may turn the dope rap instrumental into a dope song. Something people need to tune in to.
Thus discover your style, write a couple sick lyrics, along with follow your own dreams. Nevertheless the result is: without good rap beats, you're not going anywhere.
