I'm a bit confused. If we turn over the copyright to humtoo, does that mean that we can not put this music on another music library site, or pitch it too a publisher or artist? Do you, humtoo tie up that song from any other use by the writer for five years? If it only means that you need permission to use that song for five years in your library, that I could agree with, but I would not agree with you freezing it exclusively from any other use, such as recording it or being used by another library.
