Apple, Amazon, and others have all announced services that will allow you to stash your music somewhere "out there" on the 'net, and listen to it wherever you have 'net access.

What 'cloud-based music' looked like in 1892
The Telharmonium (also known as the Dynamophone) was an early electronic musical instrument, developed by Thaddeus Cahill in 1897.[1][2] The electrical signal from the Telharmonium was transmitted over wires; it was heard on the receiving end by means of 'horn' speakers.[3]
