"Handlebars" by the Flobots, while it's a bit of an annoying song, has quite a lot to say, and it gives me chills whenever I hear it.
My own personal favourite powerful song is Pearl Jam's cover of Last Kiss, and also Cats in the Cradle by Ugly Kid Joe - used to make me cry when I was little.

I know Blind Guardian, learned of them during my power metal phase. I also know that song, and I'd definately agree with you that they're powerful.
Finally!!! My life is complete. Thank you. Now I can die in peace... Well, maby not. You are honestly the first person I've heard acknoledge their pressence. I've posted about them like 5 other times in music threads and everyone ignores it.
Blind Guardian are great. I mean, what other band chooses to write songs that use up all 128 audio tracks of their recording capability?
