Before you do the radio subscription thing, check this out:

This is a free radio station that you set up to play the types of songs you want to hear. For example, you can go into the profile for your station and say you like "The Beach Boys", "Simon & Garfunkle" and "Jan & Dean". Then the station plays songs from those artists and songs with similar qualities based on what you like. You rate the songs (like or dislike) and the station will make it's selection based on your input.
Also, you can set up more than one station - I've got stations called "Los Lonely Boys" (Tex-Mex guitar/blues), "School House Rock" (for my oldest son), "Dan Zanes" (folk) (for the youngest son) - you get the idea.
And did I mention it was free?
It's really a neat way to listen to music - you might dig up some old songs you hadn't heard in a while and maybe find some new stuff to dig.
