This inspired me to write a song....

I took the melody of yours that jemmz posted, and developed it further.
The lyrics were just based on the theme of this thread.
Now, I'm not saying what I did is any good (the AlterEgo voice is BAD, but I've got a cold and can't speak never mind sing), but it does give your tune
context.
Context is important for any tune. Even if you take those 5 notes from Close Encounters of the 3rd Kind - which have no chords or anything - it
does have context in the film, and that is what invokes the emotion.
No-one knows the context of your tunes, so you have to provide one.
