Emergence of digital downloads

The music industry hasn't been the same since the birth of digital download.There has been a decrease of record sales which has resulted in musicians having to work ten times harder than usual, finding alternative ways of promoting thier music. The effect of the digital download on the music industry has lead to record companies realising singles through downloading websites such as itunes.Releasing singles download has made an impact in terms of increasing record sales, but it still hasn't made the music industry as comfortable as it use to be due to the rapid growth of music sharing softwares.As we are aware, the introduction of these digital downloads doesn't neccessarily mean progression because there is a massive sound quality difference between the music you purchase with your own money than the music you downloaded for free, therefore the emergence of digital download doesn't signal the end of the music industry.
