MP3 and P2P Stats/Data

[daniel1113]

Hey guys,

I am trying to find some statistics regarding mp3s, mp3 players, and peer-2-peer music sharing programs. Specificially, I want to find data involving the number of mp3 players sold per year, number of songs that have been traded online yearly, number of p2p users, etc. If you know of any reputable websites or organizations that have this sort of data, it would be much appreciated. Thanks a bunch.
