Cover art for Linoleum lyrics by Pain of Salvation

Sounds like a frigid anal control freakish type A personality, you know the type who bottles up all emotion and wears a mask 24/7. Well one day something/someone/an event was far out of her control and she snapped.

And after said event, even the slightest empathy shown to her by someone else causes her to break down all over again.

@I_See_sound the music also seems to be building gradually each verse before "exploding" for the chorus too ... which follows the flow of the lyrics very well.
