Well, IMHO having Sirius music on dbs is a big YAWN. As far as the bandwidth question, those 60 channels are actually taking up more space than you might think. Add in the 50 existing music stations, (or at least the 30 stereo ones) & E* is burning quite a bit of bandwidth that could be put to much better use. (but that's nothing new for them) By my calculations, those 60 channels of Sirius could instead be used for at least a DOZEN new SD video channels!
First of all, if I'm listening to music at home, I do NOT WANT or NEED a DJ chattering between songs - THAT'S why there is the song titles on the TV screen. I want JUST music - NOTHING ELSE. If I wanted a DJ, I'd turn on a FREE radio. As far as sound quality goes, it is obviously better than those mono Muzak channels, but I think the stereo ones that come directly from CD's actually sound better.
For myself, I'm perfectly happy with Music Choice on D* - the only thing I'd change on it, is if they would add "Party Favorites" & "Easy Vocals" to the residential lineup. (they already exist on the commercial packages, so all they need to do is turn them on - most cable co. that carry MC carry these already) Even the 30 CD channels on DISH is not that bad, although they do need some work on the lineup & song quantity - if they had just added a couple more formats, it might even be able to compete with MC or DMX.
