I just don't see any dangers. I cannot loose my intellectual property. I have agreed not to hold Myspace resonsible for any royalty fees for distribution of my music (words or photos) through their site and I have guaranteed that I own the rights to music (pics and thoughts) I put there (or that the music is in the public domain). These are all reasonable things to me.
A quick look at Mypspace members shows that the Mypsace contract has passed the legal scrutiny for these folks, American folk/bluegrassers: Tim O'Brien , Willie Nelson, Gillian Welch, Dolly Parton, Reba McEntire, Doc Watson, Tony Rice
And for these Celtic performers: Lunasa , Altan, The Chieftains, David Francey, Alasdair Fraser, Natalie Haas, Rachel Hair, Tommy Makem, Battlefield Band
These are just my friends or my Myspace freinds. There are many many other professional musicians who've agreed to put up their music - and there are thousands of semi-pro and amatuers as well.
What would Myspace gain by getting into an ugly distribution rights issue with me, with Dolly Parton, with Tommy Makem or with a class action suit by all of us? Would they really risk all by a dodgey intellectual rights issue for the SALE of music for any of us?
They may be evil, but they're not stupid. It is in their best interest, to take advantage of the "pull power" of our music to their site, so they can sell advertizing. That is their obvious motive - and that's OK with me.
That is obviously OK with many many other artists.
