Cover art for Baby Blue lyrics by Emilíana Torrini

Post-partum depression?

That would lead me to think this song about a mother drowning her child:

"Before my bare eyes I saw her drowning"

Then putting it in a jar and eating it's heart?

"Keep my daughter in a jar She can't get out she won't go far My heart is in my mouth But still keep pounding "

Disturbing :O
