Webcaster Settlement Act of 2009 - Prohibits the U.S. Court of Appeals for the District of Columbia from taking this Act into account in its review of the determination by the Copyright Royalty Judges of May 1, 2007, of rates and terms for the digital performance of sound recordings and ephemeral recordings, pursuant to specified provisions.

Defines "webcaster," for provisions relating to licenses for the reproduction and performance of sound recordings via webcasting, as a person or entity that has obtained a compulsory license under specified provisions. (Current law defines such term as a person or entity that has obtained a compulsory license under specified provisions to make eligible nonsubscription transmissions and ephemeral recordings.)

Terminates, 30 days after enactment of this Act, the authority to make commercial or noncommercial webcasting settlements under existing provisions.
