This shouldn't go for "extreme" variations, right? See the example:
The original recording Don't Push appears on tracks which vary in length from 3:45 to 3:55 because they have been mastered at different speeds.
The fastest version is ~1.05 times faster than the slowest, similar to difference in mastering. A track with the same recording sped up 2 times with nothing else changed wouldn't be perceived as the same recording, more like a remix (even if it isn't).
