Stunning. Simply stunning.
This is the *only* remix I have heard of the Mario Kart credits that even comes close to Sole Signal's "Days End" (ocremix.org, and somewhere here too I think), and I think you've actually surpassed it. Superb work catching the feel and emotion of the song, while adding your own little touches here and there. Honeslty wish I could give a 6/5 and a 11/10. Phenomenal...
