I used to pirate a lot of music, but nowadays i rarely do it. Because in my opinion, it's just so much easier to quickly buy them. With only 3 accounts – Bandcamp, Soundcloud and Spotify – I can cover almost all my needs in this regard. This wasn't possible only a few years ago.
Compare that to the state of tv series. I wanted to watch some HBO content recently an typed "HBO GO" into search. First result says:
"HBO GO. It's HBO. Anywhere."
Anywhere, great! click
"To access HBO GO, you must reside within the fifty states of the United States of America."
I didn't even bother trying to circumvent that and went straight for a torrent site …
Of course, a lot of people use a lack of service quality as an excuse, when they just want free content. But for those who are willing to pay, service and availability is a problem.
