The SIAE and SCF licenses take various parameters into consideration, including: the size of the space where the music is played, the number of speakers (for example inside a shop), the number of seats in a theater and etc. If you use “commercial” music it is necessary to request these licenses from both bodies in order to regularly provide sound for your supermarket; here the costs easily double.
The use of Rehegoo music does not require licenses from SIAE and SCF, but only the Rehegoo license which fully covers the rights for in-store distribution.
