Cover art for Things lyrics by Frightened Rabbit

"The point was hard to pass A mediocre past"

I'm pretty sure it's:

"Pointless artefacts of a mediocre past"

And it's definitely "through the door", not "for the door".

As for the meaning, completely agree with jemkid. What a song to start the album. You could play it right after "Floating down the Forth", it's clear he is making the next step here.
