Tough question in a way since its so difficult to separate a beautiful lyric from a wonderful melody. "Ashoken Farewell" comes to mind as it was originally done with no lyric. I remember I found it interesting to use it in Burn's Civil War saga as there were other "haunting" melodies from that period. AF has the added advantage of being a beautiful piece on damn near any instrument. I dunno'....Kazoo is probably a bit ridiculous, but.............

Also, some songs are very different at different tempos too. I've gotten comments on both "Dixie" and "Yellow Rose of Texas" on Hammered as slow expressive ballads.

Looking forward to more on this thread!!!
