Cover art for Lost lyrics by Killswitch Engage

I think it's obvious that the song is about someone who died... "it should have been me", and "strong as you were in the end"

Possibly a connection to Rose of Sharyn?

Song Meaning

@sto4000

"it should have been me" It can mean that he wants to be the guys who is with his ex-gf.

"strong as you were in the end" It can mean that when the girl broke up with him, the girl didn't gave a shit...

But it can still be what you said :)
