It's actually too much of a price. Most of on this site can gladly afford $10 a month for 12 months, but that's $120 a year. That's a lot of money for some people, and when you add people in other countries, that could be someone's monthly salary.
The price is fine for the majority of people. For those that can't afford the full price they can do this. The inconvenience of it stops most people doing it so I doubt spotify cares.
