Kyle Devine analyses in his book Decomposed: The Political Ecology of Music the environmental and social impacts of the production of recording medium from shellac to streaming. Analog and digital recording medium, as well as electronic devices for music consumption, leave a negative footprint in terms of materials, working conditions, energy consumption. He also shows that multiple streaming generates more greenhouse gases than pressing a vinyl LP. Downloading a song to a local device for repeated playback is currently the least environmentally harmful method of music consumption.
