Apple's successful digital music strategy has helped raise the entire industry, a new report claims.

In its latest annual US Music Consumer Survey, JupiterResearch declares Apple to have built awareness and usage of digital music in general in 2006.

"Use of playlists has steadily increased, and ripping music has reached a penetration rate of 25 per cent," said David Card, vice president and senior analyst. "Over 60 per cent of portable music device users regularly rip music, while 58 per cent of iPod users and 44 per cent of users of other portable music devices use playlists."

JupiterResearch surveys have shown a steady increase in the size of consumers' digital music collections over the past three years. Even so, only 18 per cent of online adults with music collections have more than 1,000 songs on their computers.

"Traditional methods of music promotion, such as radio and music videos, remain the leading influences over consumer's music purchases," said David Schatsky, president of JupiterKagan. "Music companies should market online broadly to heavy music listeners and spenders."
