OBS_VALUE: Different quotas are imposed depending on the music style and the type of radio: from 25%  to 40% of Portuguese music irrespectively of the nationality of the musicians/interpreters. However, 60% of that quota has to be made from music authored or interpretated by European Union musicians.By contrast, at the EU level, althought Directive 2010/13/EU of 10 March 2010 (Audiovisual Media Services Directive) aims to promote European audiovisual work, it does not impose any specific quotas on broadcasting local music.
