Mobile music firm Music WithMe has been helping people transfer their iTunes libraries to non-Apple devices for three years now, which the company says gives it a good viewpoint on how people are using their digital music. And? “We ran some analysis on our anonymous user data and discovered that, on average, 81% of a user’s library has never been played in iTunes. Ever,” co-founder Jeff Fedor tells Music Ally. The company also says the average iTunes library has 5,409 songs, of which 4,195 have never been played (and thus 1,214 have been). A useful stat to know, given the fact that many current cloud storage services require every track to be uploaded.
