The ProjectSAM website has an ‘end user agreement’ stating that purchase of the package grants one sole user with a licence to install, activate the product.
Music or effects from a conventional production music library do not need a user to buy software or activate a license to audition or listen to the tracks. The licence agreement is only relevant when someone makes use of the music for broadcast or other media. So, people are not violating any terms or agreements and discussion, swaps and posting of library music is mostly okay.
The ProjectSAM material does not meet the above criteria and ProjectSAM B.V. is a proprietary product.
