I'm not Spotify's greatest advocate here but why do all the comments here suggest that if he price goes up then it just mean you get more for your money.
It's called inflation. The cost of doing business for them has risen and therefore they are passing that back to consumer.
Now that doesn't prevent them from not increasing wages of course and pocketing some of that extra revenue instead of course.
It just shouldn't be surprising that things get more expensive as time goes on.
