Would an Audiofile really download music?

I can get on the internet, get to Audiogon, and post. That's my extent to my internet savvy. Where do I find out about downloading? How do I go about doing it? What do I need?

Champtree, someone posted that they use downloads to quickly check out music they are not sure about. That would be what I would do; download a few things, see if I like it and then buy the CD somewhere. I don't know how much money I have blown on music that I ended up not liking, even after reading all the reviews and tasting some samples from Amazon. Can you say Wilco?
