Juliana Hatfield - Simplicity Is Beautiful

Two songs were bouncing around together this morning. Funny that they are by the same artist. The second was "Cool Rock Boy" also by Juliana Hatfield. I couldn't find a sample to put on here.
Some mornings I wake up with several songs fighting for attention. Sometimes it's the same artist and sometimes it's several artists at once. It makes me wonder what their relationship is. Common rhythm, key, theme, what? I just don't know.
