I did this yesterday; I picked 320 / WAV / WAV / 320 / 320 / 128. I cannot distinguish 320 from WAV, so I was mostly just trying to spot the 128 and pick one of the other two. I found it a bit fatiguing to listen to so much new music. Also, it's hard to know if I'm listening to a WAV of some 808 drum loop or an actual recording of a snare/cymbal encoded. The classical piano seemed easiest to spot the 128. I listened through IEMs plugged into a Macbook Air in a quiet room and I wouldn't say it was easy.
