What is so significant to distinguish between a blog and a microblog like Twitter? Both allow publication and syndication, with moderately different constraints.

There is no single perfect solution, the best possibility is that there are many options so that listeners can pick what is most convenient for them. Customers will be interested only if the overall value is good.

There is already alot of exciting overlap between free music and P2P, that will continue to grow. Musicians can get listeners with a minimum of distribution costs, and we will some techniques like BitLet music streaming will be improved and become more popular.

There are enough different public torrent sites that even if one is taken down it would not be catastrophic. Although Mininova and others do a great job and hopefully will never stop operation, advances like DHT and magnet links mean that bittorrent would continue happily even if every single public site were taken offline, which is even more unlikely :D

If we hit that bullseye, the rest of the dominoes should fall like a house of cards. Checkmate.
