You really need to ABX any 2 of the samples at least 15 times before getting excited. If you just are just trying to guess which file is which, you might be right, but can you repeat that or was it just a guess?
Someone might correctly choose how many fingers I am holding up behind my back, but that doesn't mean they are psychic.
You got it right on one song. The next step is to prove to yourself that you can pick the right files every time.
Pardon my ignorance, but what's ABX?
