Heartbeat

"And I will a along destroy what destroys my home"

I think is,

"And I will alone, destroy what destroys my own,

Heart Beat."

I haven't settled on a meaning yet but from the lines,

"And I might be wrong But I don't think you could sing along

To my

Heart.....Beat"

and

"Cued up the major third But you don't know you just take my word"

I get the impression that the song is about being misunderstood.
