I used to own a bar once. During winter weekdays when there was less people and if I wanted to go home earlier, I would play some jazz music, usually the people would just left their drinks unfinished and just leave. On other occasions, I would put some Chet Baker concert, both on screen and on speakers, just to see the reaction. Even the regulars, more girls than boys, would come and ask for the change of music. Often, they would say that they simply cant endure so much sorrow, which is interesting. No matter how ’sad’ the music was, I would first think of it as ’beautiful’. No need to say that soon I changed my music menu, for the sake of better profit. But, even in the major cities, jazz bars are rare, or there is a lot other music there, with jazz sometimes included...just crossed my mind, back in a day, there was a jukebox in one popular bar that I went often, because the owner wanted for customers to pay for the music...to my surprise, I found out that jukebox had a Led Zeppelin concert and on it was a ’dazed and confused’ song that lasts some 25min...I would play it and went for a walk, 20 minuts later, the bar would be empty...first they removed the cd and not long after the jukebox was gone too...when I think of it, some jazz would cause the same effect, but with less noise
