Among key highlights of the research:

- Despite a relatively high average of 375 songs per player, 50 percent of digital music players hold fewer than 100 songs - suggesting a perfect target for limited capacity mobile phone / digital music player hybrids. A quarter of digital music players have 100-499 songs while the remaining 25 percent have more than 500 songs.

- 21 percent of young Americans (12-29) have a digital music player. Among those 30-49, ownership is 12 percent, and among those 50+, it drops to 4 percent.

- Apple is the leading brand with a 53 percent market share of all digital music players, with Sony and RCA tied for a distant second with 9 percent share each.

- iPod owners are big music fans: they have significantly bigger libraries (504 songs on average) compared to owners of other digital music players (246 songs).

- Motorola's iTunes phone has significant market potential for Cingular - 14 percent of Cingular's customers have a digital music player but a larger proportion, 17 percent, say they want to buy one in the next twelve months.

- Mobile phone customers are already consuming music on their phones: one-in-four Cingular (26 percent) customers have downloaded a ringtone at some point in the past (lower than Sprint Nextel customers at 32 percent but higher than Verizon at 19 percent).

- Only one-in-five (22 percent) digital music player owners bought a song online at some point in the past, suggesting a majority of the music on the devices come from owners' CDs and P2P file-sharing sources.
