There is a lot of focus and discussion around the $1.50 figure I mentioned, and perhaps I was wrong to include it in the post. The $1.50 is not the point. I would pay $1.50. I gladly pay for Pinboard, Newsblur, The New York Times, The Economist, The New Yorker, and many other online services that provide exponential value to me. And, as I mentioned in the post, I am more than happy to pay $10 a month for SoundCloud because I use it so much.
My point is that instead of even offering the option of a subscription, SoundCloud immediately went to ads that are annoying and hostile and started deleting music, forcing me to scramble to other options that are just as hostile (where hostile == "first world problem" of paying with a credit card to multiple unknown vendors) because music distribution online is broken.
