Oh, I've got one ^^
I've played a character named Aiwe in several games. Aiwe is Tolkien's elvish (Quenya, to be exact) for "small bird". She's always a bard, and I always play, or at least roleplay playing, a song called "This Little Bird". It's a duet, a hidden track on the end of Jewel's Spirit cd.
It's the second song here, begins at 4:44.
I'd adore to have it in MML.
