Cover art for Blue lyrics by Joni Mitchell

Is there a sadder song than Blue? What a metaphor...the blues (grief and sadness) under you skin so much get can't rid of it, in fact it's filling an empty space because without it the gaping space it would be just too unbearable. Just like Joni though she'll make up her own mind:"gonna take a look around it though."

All that's left is an empty shell.
