The great news is you can listen to it anywhere you have an internet connection by streaming online. They now have an "app for that" too so you can listen on your iPhone/touch/what-have-you.
You can also subscribe to their podcasts on iTunes. My favorite is the Song of the Day podcast. A new song every day! I have learned about many new artists from them.
Enjoy the tunes!
They also put on a great concert series in August at the Seattle Center's Mural Amphitheater which is free. I can't wait for this year's lineup!
