i suspect one factor is that music is a lot cheaper to produce than movies, so selling music at an "accessible" price is a lot more viable as a solution. plus, there's a larger market for music since music is largely consumed in isolation. people tend to listen to music themselves so they would either buy a copy for themselves, or stream for themselves, so there's the benefit of volume as well. on the other hand, movies are more likely to be consumed in groups - a group of people watching one movie will only pay once.
for the tv/movie industry, the best solution we have right now is basically streaming services like netflix. the issue is that its probably still not economically feasible for companies like netflix to pay for the streaming rights of new movies for their subscribers, especially those big budget movies. so for those, either you'd have to wait until the price is more palatable for netflix, or you'd have to just pirate it.
