Depends on who produced it and the quality of production.
I agree, your question isn't clear my man. It depends on what genre beat you making, club track, sampled, choped and skewd, electrica, real sounds. Then you gotta consider how long it took to make the beat, what programmes were used, then the quality and authenticity of the beat................Thats my limited understanding of what goes into it, which I will admit stands to be corrected...theres a lot that goes into it.
Like as an emcee/ ghost writer, when Im featuring on a dudes track theres a lot that has to be considered, like does the buyer want fresh lyrics or shit from my archives, what type of delivery is expected, or can I go organised flow or pure stylefree.............its crazy...
