Spotify is producing their own music because what they pay out is divided amongst any music that gets more than a 1000 plays (I forget over what time period) and the amount they pay out is a percentage of their total income. The more they pay to themselves the less they pay others. It sucks.
However, I'm on Spotify a lot but almost never passively. I usually pick an album but there are also playlists like the one that has nearly every record with a Lester Young solo-- including some air-checks. It can take most of a day to get through it. When my choices do run out I often have gotten fairly good followups.(After I played some Charles Lloyd they continued with Coltrane, Dolphy etc., at one point making a perfect segue from one to another that was so good I presumed it was done by a real person-- of course shortly after that they fired most of their programmers.)
Once or twice I have heard what sounds like an AI mix of Bill Evans, Bill Charlop and Eric Satie-- it was pretty awful.
Is it really "Spring Can Really Hang You Up the Most"? I know you can't can't copyright a title (e.g. Blue Haze) but Spring Can Really Hang You Up the Most is such an idiosyncratic use of words you'd think the composers could sue.
