I'm not religious nor do I intend to be, but they will still have my prayers also. If there is any form of afterlife, they won't suffer - only void and eternal peace awaits there, unless the soul itself wishes to return.
Count of Tuscany, Octavarium and A Change of Seasons. These are definite.
I have a lot of other songs that also get to me, but those are some of the tunes that I enjoy the most.
