I had to jump in here, to compare XM's programming with music choice is rediculous.
XM's commercial breaks are there simply to remind listeners of the great upcoming events on other channels. the breaks are like 30 seconds every 15 minutes.
Theres also 'mood breaks' on the decades channels - for example, the 40's wil interrupt the music with breaking news of the victory at Midway or the German Surrender. The 60's runns ads with Frank Sinatra endorsing JFK.
MUSIC CHOICE has NOTHING on XM for Origional content, like;
Then, Again...LIVE - a show where a classic band, in studio, in front of an audience replays an ENTIRE clasic album (recent shows have had Jethro Tull - Aqualung, Cheap trick - Live at Budakan) from beginning to end. they re-invent some songs, and share some observations about the process of creating teh work.
Artist Confidential - Rock Superstars (Def Leppard, Robert Plant, Rush) come in studio to be interviewed about thier carears by Robert Taylor Morris, and play songs from thier history
Buried Treasure - One Hour a week with Tom Petty playing songs that have not hit the airwaves in years, if not ever
VOX - A full opera every weekday noon, with Thursdays reserved for Wagner. At night you can catch full Gilbert and Sullivans.
Decades Channels - Every channel has special shows, from a Doo Wop show on the 50's to Wax Your Woodie on the 60's to Bubblegum Pop shows on teh 70's to Lost Hits on the 80's to 9oH retro - a 90's dance mix on the 90's
Squizz - Plays one track from a Brand New release every hour on Tuesdays
Audio Visions - Night Lab - a mixture of new age and nature sounds for you to sleep to.
Not to mention The BEST Live8 coverage (each of the top cities got thier own channel for the entire day), Replaying the first FarmAid in its entirety, and CURRENTLY RUNNING - IT: THE HISTORY OF POP MUSIC - where they start on the 40's channel and play EVERY pop hit in chronological order until a week later they hit 1950, then the show switches to the 50's channel until 1960 etc. etc...until a month later you have played EVERY POP HIT FOR 60 years.
Dont get me started on O&A...to compare this to the Ipod/jukebox that is MC is apples and oranges.
