The Battle Is On To Find The 2005 National Champion Of Sports Anthems! Announcing The SIRIUS Music Mayhem Song Tournament

Songs by AC/DC, Rolling Stones, Queen, Survivor are No. 1 Seeds, but Full Slate of 64 Entries Includes Other Legendary Anthems

NEW YORK – February 23, 2005 – “Back In Black,” “Start Me Up,” “We Will Rock You/We Are The Champions,” “Eye of the Tiger.” Could one of these classics be the greatest sports rally song of 2005?

SIRIUS Satellite Radio will determine that answer by asking sports fans to participate in SIRIUS Music Mayhem, a web-based game ending March 27. Sports fans will vote on their favorite arena anthem and be entered in the sweepstakes for the chance to win a trip for two to the 2005 college hoops championship, along with other great prizes. SIRIUS Music Mayhem will last five weeks, feature 64 tunes, but crown only one champion. Full sweepstakes rules and the game are found at sirius.com/mayhem.

SIRIUS Music Mayhem is the perfect marriage of two SIRIUS virtues: 65 channels of 100% commercial-free music of every genre along with the best sports lineup on the radio. SIRIUS has partnerships with more than 110 Division I colleges around the country.

Fans can now vote in the first of the six rounds of SIRIUS Music Mayhem by going to sirius.com/mayhem and choosing their favorite sports anthems in all four brackets. Winning songs in this round will compete against each other in round two beginning February 28.

Prizes will be awarded throughout all six rounds of the SIRIUS Music Mayhem sweepstakes tournament, including SIRIUS Satellite Radios with prepaid subscriptions all the way to a trip for two to this year’s college basketball championships.

“The SIRIUS Music Mayhem tournament will once-and-for-all determine the 2005 National Champion of sports anthems,” said Music Mayhem Commissioner (and SIRIUS Senior Vice President of Marketing) Tola Murphy-Baran. “AC/DC, the Rolling Stones, Queen and Survivor are the top seeds in this competition, but there are many other worthy challengers, so unless you want to see ‘Who Let the Dogs Out,’ ‘Macarena’ or ‘Whoomp! There It Is’ advance to the final rounds, we encourage everyone to play SIRIUS Music Mayhem!”

SIRIUS Satellite Radio is the premier destination for sports on the radio. For the first time in 2004, pro football fans were able to choose from a full slate of live NFL broadcasts from around the country. SIRIUS also broadcasts up to 40 NBA games each week. SIRIUS College Sports Radio will air more than 200 college basketball games in February alone. SIRIUS is also the Official Satellite Radio Partner of the NHL and Barclays English Premier League Soccer.
