Number of songs sold on iTunes in the past three years: 850 million.
Number of songs traded on P2P file-sharing networks during the same time: 90 billion
850 million iTunes songs/ 42 million iPods = 20 songs/ iPod.
Over three years that comes to people spending an average of $7 a year on music at the iTunes store.
This is from the– and is very interesting. My husband has an iPod and probably hasn’t even bought 20 songs (I think it’s more like 15) – he raided our CD collection and burned them all onto his iPod so that he could listen to more than one CD at a time in the car.
