Wow, already some submissions. If any of you want to edit your submission, feel free to, and if you want to change it to a newer one, post CLEARLY in this thread that you're changing it. If possible avoid this though; the other judges and I will probably be preparing reviews and scores in a text file as the submissions come along, and we don't want to prepare a review/score for a submission that ends up being changed.
Also, a cover is basically remaking the original from scratch. It doesn't necessarily have to be a different genre. Remixing is often used to describe making a cover but in its strict definition, when you remix a track you're just taking the original audio file or stems of the audio file and mixing it in a new way.
