I've thought the same thing for a long time, but figuring out the exact right model, a bit trickier of course. A steemit + spotify solution could be revolutionary. But steemit first really needs to figure out a way to monetize viral-type / high-quality content that attracts interaction in perpetuity, as opposed to just the first 24 hours, and to a lesser extent the first 30 days only. As for piracy, amazing to think you actually reward the artist directly each time you listen to their music, watch their video, read their stories, etc in a completely censorship-resistant fashion. That's exactly what made our youtube channel work so well, except for the flagging/blocking/censorship that made us finally give up as they tossed years of our hard work down the drain overnight.
