Creators came together as part of the Meet the Authors event in Brussels.
They argue that too often user uploaded content platforms are giving access to content but providing little or no remuneration to the creators at the base of the value chain.
Songwriter Fiona Bevan, BASCA's Crispin Hunt and PRS for Music deputy chairman Simon Darlow were among the 60 creators and composers to put their names to the open letter to the EU.
Oscar-winning composer Jan Kaczmarek and keynote speaker for the event said: 'As creators, we need to know that there is a sound framework to ensure that those who commercially benefit from the use of our works have our consent and remunerate us appropriately.
'Without this very basic principle, living as a professional author with full dedication to our work is simply not possible.'
The Meet the Authors gathering was attended by vice-president Ansip, Commissioner Navracsics, MEPs from the five main political groups and from throughout Europe, and member state representatives from 13 countries, including four ambassadors.
