If you want to play music in public, you will have to deal with both Sena and Buma/Stemra. What exactly is the difference between these organisations?
Several parties are involved in the production of music: creators and makers. Buma/Stemra represents creators and ensures that affiliated composers, lyricists and publishers receive compensation when their music is used (based on copyright). Sena represents makers and ensures that artists, session musicians and producers receive compensation when their music is used (based on neighbouring rights).
