Seth has listed 15 Music lessons on his blog. Interesting read, and worth checking out.

I personally like #13 (the second #13 mind you...... which he may change to #14 when he notices his mistake)

13. Whenever possible, sell subscriptions

Few businesses can successfully sell subscriptions (magazines being the very best example), but when you can, the whole world changes. HBO, for example, is able to spend its money making shows for its viewers rather than working to find viewers for every show.

The biggest opportunity for the music business is to combine permission with subscription. The possibilities are endless. And I know it's hard to believe, but the good old days are yet to happen.

I personally think that in the not so distant future, music/media will be delivered digitally via a subscription of some sort. Music will become a utility, much like cable tv....etc.
