Update:

I haven't tried streaming. I have only a vague idea of what it is, i.e., google a radio station on my computer, and then stream the sound through my computer.

My layout:

Computers are in a room adjacent to the living room, but no wiring connects them directly. There is cable in the home office space so that the computers have internet.

I have an AV cabinet on the left side of the fireplace, with cable, speaker wire to ceiling speakers, and AC power. There is a conduit from there to the right side of the fireplace where I presently have an "old style" TV, but plan to get a flat screen TV. It has co-ax cable in it, and I plan to add HDMI for the flat screen.

There are two speakers in the ceiling, and an extra set of wires that go to the deck ceiling so I can add speakers there, too.

It looks like Hank's suggestion for the Logitech wireless is the most practical way to get sound from my computer to my AV cabinet. Either that or dedicate a small computer to the AV cabinet.

Old school comes easy for me, since by most definitions I'm now old. I thought about the idea of putting up an old style TV antenna in a tree, etc., but no way am I cutting holes in my new house to bring the antenna wire inside. I figured by having cable wired into my AV cabinet, I'd be all set. Interestingly, none of the contractors, electricians, or stereo shop guy where I bought the speakers for ceiling installation mentioned any of these "new age" audio alternatives to me back during the framing stage when it would have been a piece of cake to install any number of wiring alternatives.

For those of you who don't listen to FM radio, how and where do you get exposure to music that you don't already have? In a conversation with my adult daughters, they told me they never listen to radio. So I asked them the same question because they are both musicians and into music. After staring at me blankly, I finally got a partial answer in the form of friends tell them. Never bothered asking how the friends learn of it.

Sirius radio, I've heard of it, on, you guessed it, FM radio. WTF is it? It means buying a new radio, right?

AP Kaiser D,

I would choose my genre and enjoy, but Comcast doesn't list my genre because my genre encompasses several while excluding a shitload of each. Yeah, yeah, just being picky I guess. Hey, if this was easy, I wouldn't have asked you guys.

FleaFlickr02,

Your suggestion wouldn't help a bit, but thank you. I already have at least two tuners. One decades old Onkyo that's on its last legs and a 4 yr old Philips from Costco that I got for reasons similar to yours. It has a DVD/CD player, so it's hooked up to my VCR (I still record TV programs on tape) and TV, the whole idea being that when I watch TV, I like the sound projected from my stereo system instead of shitty TV speakers.

Anyway, I'm so dated, this whole exercise is turning out to be a royal PITA.
