Are Spotify & Co. destroying the music industry?

Is modern streaming of music via providers such as Spotify or Apple Music beneficial or do these services harm the perception and listening to music and turn it into another simple consumer good that is taken for granted in a world where everything has to be available instantly? Interviews with professional artists (e.g. Fettes Brot), or successful music producers, up to semi-professional musicians and their perspective on things, will give a greater insight into this area. The origin, structure and development of streaming and those who offer it are equally part of this elaboration and help to better understand the overall construct in a huge industry with all its advantages and disadvantages.
