First off, just being a grammar nazi, but it is spelled "Melody." For the first part of the song, it sounds like you made random noises, but in a not random way. After a bit, it sounded like it was just repeating itself and got quite annoying. If you have ever made a Town Tune for AC:NL, this sounds like all random notes. I would try to add more to it. Right now, it sounds completely random.

You could also use a DATA and RESTORE label. It also looks nice. Sprites would be too hard for me.
