Makes sense - the music provides the stimulus and you provide the response, and that response to the same stimulus can vary depending on a number of variables....
Sometimes you have to change you
When listening to something you regard as not sounding good today but sounded great yesterday, you have to ask yourself is the problem with the source or with you? Oftentimes when I’m in such a situation I have to recalibrate my ears to accept what’s playing. In other words change my mind set.
That often works.
How about you?
