I actually, I remember that music producers having too much control about the rights of a lot of music.
I mean, it gets fuzzier when you have modern 'producers' who are basically the artist making the music, while a vocalist or lyricist sings / raps over the music they've made (which is most EDM), but the traditional production role was never considered the author, even when they were someone like Phil Spector who were huge assholes to the bands they worked with about exactly how their music should end up sounding, and had huge amounts of control in authoring a specific and distinct sound.
