Test the hearing and / or audio or guess the bitrate (now with the answers!)

I have repeatedly heard from people the assertion that they can easily hear the difference between the original track and the same track, but in mp3, with a bitrate of 256 (some even say 320).
I did the following - I recoded the original cdrip tracks into 4 different bitrates - 128,192,256,320.
Then the same tracks were decoded back. Next will be given links to these decoded tracks + link to the original in random order.
I propose to arrange these tracks in descending order of quality. I assume that the vast majority of people are unable to distinguish 256 from cdrip, personally I could not even distinguish 128 from cdrip when listening to tracks on an ipod. Try to convince me otherwise :)
There will also be a link to the archive with a password, which contains mp3 in 4 bitrates, a decoder and a text file indicating the bitrates.
The password for the archive will be posted later, so that anyone can verify that there is no cheating by decoding the mp3 to wav data in the archive by the decoder and comparing the received files byte-by-by.
As a test track, the classic is taken from a quite authoritative source, later I will inform what.

One file: tracks.zip (Added)
Or each track separately:
track 1.wav
track 2.wav
track 3.wav
track 4.wav
track 5.wav

(Added) Answer:
track 3 - original
track 2 - 320
track 1 - 256
track 4 - 192
track 5 - 128
