I have never heard a "Classic commercial". What channels are you listening to?
I also don't think I've ever heard the "XM Family Plan" or other such promos on music channels. The talk channels have TONS, because they have to cover the commercial space on external stations. (Or in the case of High Voltage, they have to give the hosts bathroom breaks.) Maybe my brain just skates over them because I'm used to hearing them so often on High Voltage and Extreme XM.
In any case, I think the inturruptions on the music channels are minimal at worst. I guess I can understand how some people feel since DirecTV is actually REMOVING MC. When DISH added Sirius, it was just a bonus...they left the other channels alone
It's funny, I've seen both arguments- always from people who have never listened to XM. Some say "I'm not paying to listen to DJ Chit Chat!". Others say "I'm not paying to listen to someone elses I-Pod...I like a station to have personality!"
XM actually hits a nice medium- most channels have a definate personality, without actually wasting time on talk. For example, "Lucy" and "Fred" are both "classic alternative" channels. They focus on slightly different time periods, but they still overlap about 10-15 years. Yet I can tell you which one is playing within two songs, even without a station ID.
As I write this, I have "Lucy" on. I have heard exactly ONE 10 second ID in the last 20 minutes. No Announcers, no XM Promos. I'm going to leave it on for a while and check back later.
