MySpace has announced a deal to use Gracenote's filtering technology to block unauthorized music from the site. (press release) Exactly how Gracenote filters and allows copy written material that may have been loaded with an indie artist permission is not clear.
Can YouTube survive without copy written content? And how will MySpace be effected if it only carries "authorized" and obscure indie tunes? But perhaps the biggest question is why aren't the content providers smart enough to just insert ads or links and let the content stay up on these incredibly popular and viral destinations?
