Album sales: down 15% to 430 million units
CD sales: down 20% to 362 units
Digital album sales: up 32% to 62.8 units
Track sales: up 27% to 1.07 billion units
LP sales: up 92% to 1.9 million units

In 2008, growth rates for both tracks and digital albums nearly
converged around 30%. The bad news is the days of explosive growth
rates are gone. The good news is unit increases get bigger while the
growth rates drop. With no new retailer or business model on the
horizon, and with iPhone applications better at free music services
than enticing purchases, expect digital growth rates to continue their
downward trajectory.
