Musopen is an online music library of copyright free music (public domain music). They want to give the world access to music, without the legal hassles so common today. There is a great deal of music that has expired copyrights, but almost no recordings of this music is in the public domain. Their aim to record or obtain recordings that have no copyrights so that their visitors may listen, re-use, or in any way enjoy music. Put simply, The site’s mission is to set music free.

This sounds very good. But compared to before the introduction of the Grooveshark,  BeeMp3, gimado:又一个音乐搜索引擎, Songbeta, The Hype Machine, Songza etc… Musopen site design style more like a blog, rather than providing a public service site. Perhaps I was too demanding, but I would like to Musopen group is willing to accept advice.
