The music industry is facing a transformation due to the digitization of music and the rapid distribution of data through compression over the internet. Music is available everywhere and can be quickly downloaded from the internet to mobile phones. Since the late 1990s, the music industry has been struggling with declining revenues, particularly in the traditional area of physical media sales. The music industry needs to break free from its traditional framework and combat the declining sales figures with new strategies. It is essential to acknowledge the changing times rather than resist the changes. Furthermore, major labels are losing vast sums due to data piracy and illegal downloads on the internet. The aim of this study is to provide the reader, whether a layperson or an expert, with a detailed overview of the music industry, including the music market and its various developments.
