If there IS as sample, you better hope it's NOT noticible!!! It techically IS the labels responsibility, BUT now a days labels will NOT even give you your first half unless they CAN clear the sample, AND your not getting ANY publishing so thats why most cats in the game now are using musicians to re-play things. Your going to have to do this to make MONEY. The ONLY time I ever really sell sampled beats is to Independent labels that are under 10,000 units. But then the payoff is ALOT less then a Major. So unless your selling to someone like Jay-Z, who has the BEST sample clearance team in the business. You'll be on the Independent label grind!!!
