According to the AFPI, the music biz made $US3.7 billion on digital downloads in 2008. Too bad that was only on the 5% of downloaded music people actually paid for.
Despite this being one of the foggiest of the foggy statistics to track (quantifying a black/gray market is pretty tough), the IFPI's 2008 report (basically, they're the international RIAA) does estimate that only 5% of the music we acquire online is purchased legitimately. I mean, it makes sense to me, but it's good to put that number in perspective some time.
How about a New Year's resolution to support the bands you love by buying something from them, directly if possible? I know my music karma could use a positive jolt. [IFPI Report (PDF) via BBC, CrunchGear]
