If you want to rid yourself of that vice, it's a mixed bag. For example, I usually preconceive a remix track as having the same note key, time configuration, and measure span (I know I have the terminology wrong, but I don't know the correct words) as the source material. Unfortunately, I also pay heed to the environment the ReMix is suited for. A case in point is Hedgehog Heaven: Cavern Escape. The first half of the track sounds really deep and dark, like is suited for a vast cavern, but the second half... I didn't think the piano sounded proper for such a track.
