The best method of selling sample beats on soundclick is by having a flashstore or a third party beat selling store enabled on your soundclick. If you make original beats as well, put them in your soundclick player, then attach your flashplayer and selll your sample beats like that on soundclick. Soundclick just doesnt want any copyright infringement going against them, once its on another flash player, your good. Since that flash player is not a part of soundclick directly, you are allowed to sell your sample beats like that.
