Seven links. One court case. All fighting over an essential point of copyright law that can drastically impact earnings.
One party (Flo & Eddie, Inc.) are attempting to get certain State Courts to make unilateral rulings bypassing a lawmaking body that has already spoken for the people.
The other parties — including Pandora (as defendant/appellant, university law professors (2 groups), the National Association of Broadcasters, Sirius, XM, and four other groups that deal with copyright — are fighting against Flo & Eddie, Inc.
The Big Lesson you need to take away here is this: All these people and organizations and professors are fighting over a point of copyright law because it is important to being profitable in the music business.
So, The Big Question you should answer is this: Are you giving away your rights to your songs by not taking care of the complete and proper documentation of each and every one of them?
