Sirius Filth Not Limited to Howard Stern?

I just got Sirius satellite radio a few days ago for my car. Then I discovered I could listen to some of the stations online while working from home, which is what I do... I was enjoying it until I heard something shocking- so I immediately went to Sirius.com and wrote them the following note:

I was offended by the altnation dj's comments about "taking it to the next level with your sweetheart and getting some anal action" today at 1:24 PST, just before the U2 song. I realize sirius is unedited, etc. but if I wanted to hear that kind of thing, I'd listen to Howard Stern.

Is it possible I could listen to alternative music without having to hear that kind of filth? Consider that not all your subscribers are into that kind of thing. In fact, since the radio displays the artist and song title, why do you need DJ's at all? Especially if they're unpredictable. Thanks, B
