Maybe I'm either really old fahsioned or I am an incurable romantic... but certain songs just move me with their beauty. Some prime examples, are:

Into the West, by Annie Lennox -
As a Lord of the Rings fan since childhood, the movie trilogy had a special magical place in my heart to begin with. But, when the series ended with that beautiful song at the end, it all just resonated deep within me. It seemed to sum up so well, the passing of the ancient age of fantasy and legend and the rise of history as we know it.
It still brings a slight tear to my eyes whenever I hear it, and I wouldn't have it any other way.

We Must Believe in Magic, by Crystal Gayle -
I first heard this song on the Muppet Show when I was little... and I thought Crystal Gayle was so, so beautiful. This song really speaks to me now as an adult, though. It's about magic, and how if we put our faith in it and in our capacity to be amazed by wonders, even if it seems mad, then we will be alright. People grow up, but we should not ever lose our childlike capacity for wonder and the magical. That is why I love this song so.

Stones, by David 'Iolo' Watson -
This song has a lot of history for me. It is a medieval, instrumental piece (although there are words for it) from the Ultima series of PC games.
I grew up with that series, and played every game through to it's conclusion in Ultima 9. And every time I hear Stones, I feel so much nostalgia! No other tune from a video game has the same feeling for me. To call Stones a magical melody is truly an understatement. It is a moving piece of music.

Original Sin, by Taylor Dayne -
While I don't consider myself a 'bad boy' by any means, this version of the classic song performed by Meatloaf originally is just something special for me. I suppose we all have a dark side, and to me... this song shows that darkness doesn't have to be bad, to be good. I first encountered this song when I saw the movie "The Shadow", and I've always had a place for it in my heart since the first time I heard it. I probably always will. ;)

Girls Just Want to Have Fun, by Cyndi Lauper -
Okay, so maybe I'm a product of the late 70's and the whole of the 80's, but I just love this song! You don't have to be a girl, to feel so good when you hear Cyndi singing this. It just has a light, happy vibe to it that for me sums up everything I think the 80's should have been, but wasn't: fun. Not that I didn't have my fair share of fun back in the day, but I mean the decade as a whole. At any rate, this song just makes me smile, big time.

Well, for the sake of brevity, I'll have to cut the list short at these five. I could think of a fair assortment of others... but five is a good number and we wouldn't want too long of a post. Perhaps some other time.
