The Elliott Smith song "I Didn't Understand." This is the last track on his album XO. It is a song using only vocal tracks--no instrumental tracks were used on the recording of this song. It is often compared to the opening portion of his cover of the Beatles's song "Because."

Tonight, tomorrow and everyday
