Agree with most of that, but it is sorely misplaced to think that Taylor Swift is sitting in the poor house. Spotify was only one source of income for her and her labels. Apparently not a big enough one
Secondly it is strange that she, and music artists in general keep quoting that "everyone is complaining that music sales are down." The general public isn't complaining about that, it is just all the parties with a vest financial interest that are saying that. The consumer always wants to pay less.
Crap, I mean even artists who continue to refuse to have ANY kind of digital sales for various reasons, like Tool for example, well they are doing JUST FINE, believe you me. Every album platinum. If you make good art, it will sell.
