Weedshare.com. This is a system that artists can opt into. Once in, their songs become available as "weed files" (no, not that kind of weed - think something that spreads like a weed). Now, weed files can be played up to the 3 times for free - a try it before you buy it model - after the third time, you can either purchase the song or stop playing it. With me?
Here is the kicker - the rights to this song are resident with the song and not with any particular site. That means, as a person with their own site, if I buy some songs from Weed, I can put them up on my site for others to buy. When other people, seeing my clear genius in music selections, buy those Weed files from my site, the artist still gets their cut, whoever I get the files from gets a cut, Weed.com gets a cut and I get a cut.
Think about this folks...imagine everyone creating learning objects and registering them with "Weed for Learning".com....Now you just hang a little sign out on your Web site "Learning Objects For Sale" and even if their not yours, its still legal because the original author has registered with Weed for Learning (no, it doesn't exist yet). Let's run with this a minute...so how do you find them, still stuck with massive results on Google right? No, now we start using social tagging systems like del.icio.us to create tagged, online, distributed, legally distributable, commercially viable libraries of objects.
