PFF, being a hand-to-mouth think tank, does not have $2,995 lying around -- but if it did, I might be tempted by this report on Digital Music Futures 2007-2011. This is not really a recommendation, because I know nothing about the company selling it. But the blurb piques interest:

Almost every major development in the global music industry in recent years has been with digital music. As many big brands have entered the market with significant technical experience and substantial marketing budgets, we see the next few years as the ‘Clash of the Titans’. As these huge brand names - music companies, consumer electronics manufacturers, mobile network operators, mobile handset vendors and of course all manner of advertisers - meet and compete in this growing market, this report looks at how these players are positioned to build themselves presence in the digital music market over the next five years. No doubt there will be winners and losers in this battle, but the overall effect of the interest of so many major global corporations will be renewed market growth. This report forecasts the expansion of the digital music market between 2007-2011.
