I guess back in 2007 it was worthy book to read, at least to wake up and jump on the train of digital music. But now authors should seriously re-evaluate this book with "future" tendencies. To sum up the main idea: choose streaming, instead of selling!
Ok, streaming is probably a solution. Probably, because I don't see how the majors will feed their artists, if p2p fans will pay let's say $15 for unlimited access to media? It's too little to have cost recoup! And what about jailbreaks of streamed media? It cuts again your commission.
It's weak book for the Berklee college of music, and I'm suspicious that it was build up for the Online Berklee course "The Future of Music and the Music Business" where this document is required. I'm wondering what you can learn further about Future of Music for friendly $1400? Personally, I would prefer crash regularly on MIDEM and catch up with visioneers there for that money.
