First of all, it is important to differentiate between an Independent Artist and a Do It Yourself Artist. While the independent artist is distinguished by the fact that they own the rights derived from their creativity (i.e. compositions and recordings), the DIY artist is characterised by the fact that they manage the tasks related to their own artistic and economic development.
In other words, the independent artist is independent to the extent that they own their work, so it is they alone who decide to whom to assign the exploitation rights and under what conditions. Whereas the DIY artist is a specific category of independent artist who, in addition to having ownership, takes control of the exploitation of their own work.
