Yeah I think it's easy for up and coming musicians to blame Spotify for their financial woes, but as someone who was an aspiring musician in the 90s I can tell you it was no picnic back then. Everyone I knew was broke, so the only way to make a record was to get signed, and that involved playing shows in front of A&R people which meant finding venues etc - all on your own dime. If you did manage to get signed and get an advance, you probably used it to buy better instruments and maybe pay rent for a month or two but it didn't last long. Then if you were lucky and the label decided to distribute your stuff, you'd make about a dollar between you for every full length album you sold. Music has never been about making money. You might as well play the lottery if that's your goal.
And as a consumer of music, I am very happy to be paying $14.99 a month for access to a collection that would have been virtually impossible for an individual to assemble 20 years ago. Music has been opened up to people in a way that did not exist before Spotify. Also, a good deal of the music I listen to is stuff I had already bought on CD or vinyl years before, so those artists are getting paid twice for me listening now.
Bottom line is it's always been hard to break through into making money from music. Nothing has changed except the way it's distributed.
