I'm a channel flipper. I listen to music. No talk shows, no sports, no commercials, just music. I had Sirius for a year and liked it. I thought the music channels were pretty good, but several I listened to had short play lists. W/o commercials, you can hear some popular songs every 2 hours. Good if you like those songs, bad if you don't.

I have XM at home through DirecTV, but haven't listened to too many stations. XM's country seems to be better to me than Sirius. I also like to put on Watercolors (Jazz) when I'm doing things around the house or entertaining.

As for investmenting, price per share is a meaningless number. Return on investment has nothing to do with the cost on any given day. I'd learn as much as you can about any company you plan to invest in. Learn what sharholders think about a company, not what customers think about a company. The too often do not agree.
