Digital-music player sales in the United States will grow 35 percent this year to 18.2 million units, according to a Jupiter Research report released earlier this week. The "U.S. Portable Music Device
Forecast" predicts growth will remain above 10 percent for the next few years, with annual sales hitting 29.7 million units. The installed base will then reach 56.1 million units, according to the
report--compared with 16.2 million now--making MP3 players commonplace. Jupiter's report estimates that 90 percent of U.S. consumers have 1,000 or fewer songs in their digital-music collections, and
60 percent have less than 200.
