First, the 1880-2008 lifespan. First, I wanted to point out that before audio recording was invented, the idea of owning music was absurd. Second, really I could have dated the death date even earlier. So many millions of people already steal music that ownership is pretty much dead alredy. My point is that the monetization of music can exist in many ways in the future, but selling ownership of copy won't be one of them.

Secondly, my vision does not necessarily mean the big wireless jukebox in the sky. You could also, in theory, have a portable device with every song ever recorded stored in local memory, with perpetual updates of every new song ever recorded in the future. All together the total corpus of recorded music isn't *that* big (a few terabytes?), and given the rate of technological advancement I predict (by just gut feel) it could be a reasonable idea in about five years. The monetization in this networkless business model would be no different than with a wireless delivery mechanism -- the UI of the device. It's not about the technology, it's about the user experience.

Cheers!
