Ooh, nice. It feels like a sun-dappled city full of high-arched bridges to me... though also as though it would be a good song for travelling the countryside between cities. Versatile, upbeat, charming.
I have a Firefox extension that will let me download from YouTube into .flv format, which iirc I can then convert into .ogg files, but as I'm using Chrome at the moment... any chance you can upload a ready-made .ogg file of the song? Maybe as an attachment?
Also, if you're releasing the song for others to use in KS levels (...are you?) do you want to be credited simply as 'Guyguyextreme'?
