XM to Expand Nashville Presence with New Sommet Center Studios

Washington, D.C., August 28, 2007 – XM, the nation’s leading satellite radio service with more than 8.2 million subscribers, today announced an agreement with the city of Nashville to expand its presence in Music City with new studios located in the Sommet Center’s arena tower. Construction on the new space is scheduled for completion later this year. XM’s current Nashville studios are located in the Country Music Hall of Fame.

The new facilities will include significantly expanded broadcast and production studios, as well as a dedicated performance studio, full production suite and office space. XM will use its new Nashville studios to originate its country music programming, as well as content for other channels. Additionally, XM has also teamed up with the Nashville Convention & Visitors Bureau to collaborate on free, live music events for Music City’s Visitor Information Center which is located on the main level of the arena tower. XM’s original performance series, “Music City Connection: Heroes Behind the Hits," is produced by the Nashville Convention & Visitors Bureau.

“The new Nashville arena tower studios will enable XM to provide more of the live performances, exclusive interviews and original shows that country music fans have come to expect from us, as well as the opportunity to broadcast other non-country music programming," said Eric Logan, executive vice president, programming, for XM. “The Country Music Hall of Fame has been a wonderful home to XM’s Nashville studios for the past six years and we look forward to continuing our relationship with them in the future."

More than 900 country performers have come through XM’s Nashville studios for live performances, interviews and more. Currently, XM carries seven different country music channels: “America" (XM 10) for classic country; “X Country" (XM 12) for progressive country; “Willie’s Place" (XM 13) for traditional country music; “Bluegrass Junction" (XM 14) for bluegrass music fans; “The Village" (XM 15) for folk music; “Highway 16" (XM 16) for current top country hits; and “U.S. Country" (XM 17) for 80’s and 90’s country hits.
