So the #1 record on the Billboard top jazz albums chart is:
#1 A Beautiful World - Kermit Ruffins & Irvin Mayfield
(h/t to PJ)
Buyers of this record must reflect a different demographic (i.e. older) than other stuff I have looked at on these charts since the songs on the record have done *nothing* on Spotify (to speak of) despite being a beautiful song with vocals by Haley, the title track hasn't done much on YT. Of course, one can move up on the jazz charts with modest sales.
ITunes charts
It comes in at #48 on the iTunes jazz albums chart.
