While exact numbers aren't disclosed, I've seen a $0.004 per play royalty thrown around enough that it's probably at least ballpark.
"For a 99c sale of a track on iTunes an indie artist gets 70c. At the time you need 140 Spotify streams to make the same 70c." (Source: http://www.spotidj.com/spotifyroyalties.htm)
These figures are hardly comparable with piracy, and for an artist with a reasonable audience, should more than exceed the $.918 average royalty for a song per unit sold that record companies provided in the era of CD sales.
1) It's not available where people want to watch it
2) It's not available for a price they want to pay
It's a fascinating problem, really. I doubt movie studios will ever be able to meet the "free" demand, but piracy in general has put all sorts of pressure on them to get movies into peoples' hands quicker. The Hunger Games was a huge hit and will be on BluRay within about 5 months of its theatrical release. It'll be out on iTunes at the same time.
Historically, this is a vast improvement. Titanic took about 10 months to go from theater to VHS. This was back in the day when places like Blockbuster had exclusive rental windows for a while too, so it was more like a year before non-pirates could purchase it for home use.
If people could reliably pirate high fidelity copies of movies between the theater and DVD releases, I suspect that timing would shrink even further.
An example: the Daily Show is available on the Comedy Central website, but it doesn't work well in all countries due to the nature of their streaming method (buffering.. buffering..). What level of piracy is it, to open the Daily Show website, be exposed to their ads, then actually watch it from another location? Another amusing point on this is, if you watch it in the U.S. you are presented with ads at the breaks. Watch it in Mexico: no ads.
Have we not already come to the agreement that the problem is not piracy, but the lack of access in our new global arena? None of us here would be so naive as to believe that piracy will end when each of us have access regardless of our geographical location, but at least then we will be able to have a real conversation about it.
