BitTorrent's experiments with paid music and video bundles have clearly seen some early success -- and accordingly, it's opening up the floodgates. The peer-to-peer service now lets any artist apply to distribute content through paywall-based downloads, whether they're releasing music, apps or movies. As before, the allure is the sheer flexibility that artists get in deciding not just what you pay for, but when you pay for it. A musician might let the first 500 downloaders listen to an album for free, for instance, but can ask latecomers to pay for some or all of the songs. They also get 90 percent of the revenue instead of the 70 percent they get from most online music services, so there's a chance they'll take home more money if they produce a hit.
