The NPD Group has a new report that states that in 2008, 87% of all digital music buyers in the U.S. used iTunes while 16% were purchased through Amazon MP3. Analyst Russ Crupnick says that being in second place is encouraging considering that it has only been around for 18 months.

“It used to be that iTunes was first, and second was practically nobody,” Crupnick said. The survey also reported that many of the consumers are older and still purchase CDs.
