This article is bad and the author should feel bad.
1) The conversion rate doesn't need to be even close to 1:1. Spotify makes 87-91% of its revenue from the customers that subscribe (depending on what report you read). This is despite the percentage of people paying is around or less than 25%. I've read that Spotify would be profitable if it could just get freemium users to pay $1/3 months.
2) Psy was rich before he was available in North America. The article makes it sound like exposure to the west MADE him. That's exceptional cultural egocentrism.
3) Consumers don't DESERVE free music.
A lot of people on here (rightly) say that nobody DESERVES to make a living being a musician, and that's fair enough. But nobody DESERVES free music, either. But it DOES take work and money and time to make music, so if you're going to listen to it, you should pay for it, one way or another. The thing I can't stand is people listening to music with no intention of giving back. If an artist makes music and nobody listens to it because the music isn't good, or they didn't do a good job spreading the word, well, fair enough. They don't deserve money for that. But I'd be pissed if my company decided to use my work without paying me, and it's understandable that artists (and to a more limited extent, labels) want to be paid for what you're consuming.
If you don't listen, you don't pay for it. Fine. But if you're streaming someone's music, *you should pay for it*. It's not free to make. If you don't want to pay, YOU DON'T GET TO LISTEN. That's the way it works for everything else in your life. Don't want to pay for an Apple Watch? You don't get an Apple Watch. Don't want to pay for a car? Walk. You're not entitled to music just because it's easy to obtain.
