I have mixed feelings about this stuff. While being able to easily share files is incredibly convenient and fun when used responsibly, it's also being abused to a level that really hurts some people. The singer who gave me my first opportunity to have a couple remixes released did so through her own start-up label. She's an established vocalist who's been featured on tracks by people like A Guy Called Gerald and Dyad10 along with others, with relative hits like last 2001's
"Sugar (Sweet Thing)". But when she released her own album and singles last year, which required personal investment and sacrifice, she made no money at all because the releases were immediately made available for free on P2Ps and torrent sites by some jerk-offs. In fact, she lost money and is now probably shutting down the label as a result. On a personal level, the last time I spoke to her, she sounded pretty crushed about it, and is struggling just to make ends meet.
So it's tempting to think that shutting down these file sharing sites is just because big businesses are protecting their fiscal interests, but it's far harder on the little guy based on what I've seen - thanks to the assholes of the world who don't have the common sense or decency to realize how their illegal actions hurt the lives of others.
