With the rising popularity of music streaming platforms such as Spotify, Apple Music and Google Play, there are now fewer reasons to purchase songs and albums individually. This is to the dismay of several artists who claim they are being robbed of the total revenue they deserve for their work. Their argument is similar to the following analogy: you do not go into a clothing store and pay an entrance fee to then collect all of the items you want. This is what they feel listeners are doing when they pay a monthly fee to use services like Spotify Premium and Apple Music. They also think it is not fair to other fans who go out and buy their CDs when others just wait to listen to it for free online.
