:::::LOL about Diamonds. What probably happened there is that she wrote the song and had it published with her music publisher (whichever company that is). Then Teairra Mari's A&R; guy found the song while scouring the publishers for material and acquired the rights to record it for Mari. Under the law of most Western countries actually, you cannot block someone from singing/covering/recording your song, nor does one need express, written consent from the writer. It's just a freedom we have, and it allows for live performances to be possible and for shows such as idol to be possible. Therefore, in the business, it does not have much to do with the label, Myspace, directly. As for the 3-way, the logic is a bit antithetical because if the quotes say 'acquisition', then why would the previous label still be a part of it if its rights were sold off?? So yeah I see where you're coming from, but sooner or later it will clear up once more information becomes available leading up to release, so no worries.
