I don't disagree with your post, but I'm having trouble seeing how it relates to mine.
I wasn't saying you can't make good or valuable music companies. I'm just saying almost none of them make a decent profit, and therefore I won't touch them.
I mean, satellite radio was basically built on talk shows.
Or Pandora, the current winner in internet radio, from their IPO filing: "The company has brought in $90.1 million in revenue as of the first three months of its 2011 fiscal year and has lost only around $300,000." (VentureBeat)
It's an industry where even the winners are failures.
There may be some confusion here, ra means "killing it" in the inverted slang sense. "Killing it" here means "laying waste to all before them," rather than "destroying their own business model."
It seems to me that Spotify are killing it.
