Washington D.C., March 27, 2006 -- XM Satellite Radio (NASDAQ: XMSR), the nation’s leading satellite radio company with more than 6 million subscribers, today unveiled its new channel lineup that will expand the total number of XM channels to more than 170 with the addition of 10 new commercial-free music channels and seven regional news and talk channels coming this spring and summer.

“Our programming lineup demonstrates the depth and breadth of XM’s industry-leading content portfolio,” said Eric Logan, executive vice president of programming for XM Satellite Radio. “We continue to expand programming with our first-ever regional news and talk channels, innovative music formats, plus 10 new music channels that demonstrate XM’s firm commitment to providing the most choice and most channels in satellite radio.”

XM HAS THE MOST COMMERCIAL-FREE MUSIC CHANNELS

Overall, XM’s new channel line-up has 69 commercial-free music channels, the most commercial-free music channels in satellite radio. XM added two new commercial-free music channels on March 1: Big Tracks (XM Channel 49), focusing on classic rock from the late 70’s onward, and XM Chill (XM Channel 84), devoted to Chill music. During April and May, XM will bring the total number of new commercial-free music channels to 10. These new channels include the return of the heavy metal channel XM Liquid Metal by popular demand. The new commercial-free music channels on XM are:

# Big Tracks (XM Channel 49): Classic Rock from the late 70’s onward
# XM Chill (XM Channel 84): Chill Music
# U.S. Country (XM Channel 17): Country Superstars of the 80s & 90s
# Flight 26 (XM Channel 26): Modern Hits of the 90’s & Now
# XM Hitlist (XM Channel 30): Today’s Hit Music
# enLighten (XM Channel 34): Southern Gospel
# XM Liquid Metal (XM Channel 42): Heavy Metal
# The Heat (XM Channel 68): Rhythmic Top 40
# Escape (XM Channel 78): Easy Listening
# Viva (XM Channel 91): Latin Pop Hits

NEW REGIONAL NEWS, TALK AND MUSIC CHANNEL CATEGORY

XM will introduce six new regional news and talk channels that will, for the first time, bring XM subscribers regional news coverage for every area of the continental U.S. These channels will be added to the line-up during the late spring/early summer period. Details about the new channels will be announced prior to launch. They will complement the recent addition of Cincinnati’s tri-state news radio station WLW (XM Channel 160).

All seven regional news and talk channels provided by Clear Channel Communications will comprise a new category on the channel guide called “Regional News, Talk & Music Channels.”

This new category will also include Clear Channel-programmed music channels KISS, MIX, Nashville, and Sunny, plus the launch of WSIX, with acclaimed country personality Gerry House live from Nashville. As previously announced, Clear Channel will start carrying commercials on these music channels in May, so they are grouped separately from XM’s lineup of 69 commercial-free music channels on the new channel guide.

“OPRAH & FRIENDS” ON XM STARTING IN SEPTEMBER ON CHANNEL 156

The recently-announced Oprah & Friends channel will debut on XM channel 156, beginning in September 2006. The channel will feature a weekly reality radio show with Oprah Winfrey and the editor-at-large of O, The Oprah Magazine, Gayle King, as well as programs hosted by Oprah’s friends, all experts who appear regularly on “The Oprah Winfrey Show,” including exercise physiologist Bob Greene, author Marianne Williamson, psychologist Dr. Robin Smith, heart surgeon Dr. Mehmet Oz, and interior design expert Nate Berkus.

BOB DYLAN’S XM SHOW DEBUTS IN MAY ON “DEEP TRACKS”

Bob Dylan will host a weekly, hour-long music show exclusively on XM beginning in May on XM’s deep album rock channel Deep Tracks (XM Channel 40). The program marks the first time the music legend has ever hosted a radio show. The show features an eclectic mix of music hand-selected by Dylan. He will offer regular commentary on music and other topics, and interview special guests, including fellow musicians.
