And, each of us (hopefully audiophiles, audio enthusiasts) should always have/bring
his/her own consistent "reference/sampler music playlist/tracks" throughout our long-year audio exploration journey including tuning of our audio system at home and the audition sessions at HiFi audio shops dealers and manufacturers.
In my case, I always have/bring my
"reference/sampler music playlist intact 60 tracks" for which you can find the summary posts
here and
here on my project thread. (I also started
an independent thread on it.) Of course, several excellently-recorded vocal music tracks (focus of this thread) are included.
I always use/keep/bring also all the tracks of
"Sony Super Audio Check CD (ref.
here)
"; just for your reference, now we have
an interesting thread on pink noise (and white noise).
