What is the difference between DEM and DRM? Follow
DEM
Performance Rights: they're due every time your music is played - for performances in front of an audience or in a movie theater, for public broadcast on the radio or TV, for online use or in the digital music environment.
DRM
Mechanical Rights: they accrue every time your music is played on any medium - radio and television recordings, video and phono-mechanic reproduction or music DVD, downloads, and streaming.
