When you purchase exclusive rights to use instrumental music here on Beat Brokerz, you are taking the ability away from other recording artists to license and use that instrumental music. After the sale of a license which includes exclusive rights, the beat is de-listed in the marketplace and all licenses for the beat become unavailable for purchase.

You should also be aware that exclusive rights to use a beat are not necessarily permanent. Since licenses can expire when certain limits are reached, exclusive rights can expire along with that. For example, a license that includes exclusive rights and a license term of 2 years, would grant you the exclusive use of that instrumental beat for 2 years... at which point your license would expire and the beat could be licensed again to other artists.
