When making a cd full of your beats, ( is this what you do ?) if putting them on soundclick, any website where you can put your stuff up to show it..

what do you do with your beat, do you take a certain area, and put that up.. or do you put the first half, first minute ..

if putting them on a cd full of your beats, how much of each beat do put, do you put like the best certain time..etc.

what is the best way to do this.

how do we do this ?

There is no rule on how to present your music..

Do good music and you will get props...it's easy as that.

As for record labels and rappers...most ppl tend to listen to the 10-15 first seconds of a beat and that's it. If you don't want them to lose interest, you better make sure that your intros have something to offer. Most beat-maker put a intro version of the hook at the beginning to show what the beat is all about.
