This provocative test serves two purposes: to raise the awareness of what has happened to our music's dynamic range lately, and to question the need for a 24-bit digital audio as a delivery format in such a context.
Differences between 8-bit audio files and 16-bit are audible though - and are demonstrated here - but only marginally when it comes to most of the music that people are listening to nowadays.
One of the world's biggest modern hits - Psy's Gangnam Style - with its original 16-bit version, and its 8-bit down-converted sibling.

|Listen to [?] then vote — multiple guesses not allowed (your vote triggers a new draw)|
To pass a blind test, you will need to perform 10 trials at least, obtain a high score and reach a high confidence level: 95% is standard to rate statistical significance. It means that your score outperforms random guesses by 95%. There is still a probability that you just got lucky though, 5%. To reduce such probability to 1%, keep testing until you reached a confidence level of 99%.
