Pandora Radio is a free on line radio station. Actually it’s several radio stations. You can even build your own around a favorite artist or genre of music. Create an account, log in, pick your favorite music, and listen.
It doesn’t get much easier than that, does it?
In the Country section there are several genres and sub genres of music to choose from. The musical selections include well known and not so well known artists. I’d guess that the others are set up in a similar fashion.
