Re: "claims people make about their future behaviour doesn't reflect real-life"
Streaming music apps like Spotify are so close to being perfect it's untrue. All we need is properly decent, ubiquitous mobile broadband. Especially in the countryside when I'm thrashing the motorbike.
When we have that (mainly because I listen to music either at home or on the go -rarely somewhere where I don't have either local storage or wifi), I'll happily sub to one of these.
The question really is which bloody one! I had the same problem choosing between Netflix and LoveFilm.
