I've added a playlist to the blog sidebar. If you find it annoying there are a couple of things you can do: adjust the volume on your computer's speakers, or press the pause button in the playlist.
If you want to listen to the playlist at another time you can click POPOUT PLAYLIST. This will take you to a stand-alone playlist that you can listen to in the background. You can even bookmark it, and just return to the playlist. I just discovered this feature. When I go to blogs with music I like I often do this now if I really like the music.
