The commercial focus of smooth jazz is hardly something new:
I own records of Gene Ammons playing things like "Papa Was A Rolling Stone", "Ben" (the Michael Jackson song), "Plaqy Me" (Neil Diamond) and "Theme from the movie Fuzz"
Yes, that was Ron Carter on bass...
Ella Fitzgerald recorded "Sunshine Of Your Love"
Dave Brubeck recorded "Dave Digs Disney".
Jimmy Giuffre recorded an unusual album of songs from the musical "The Music Man" (i.e. "76 Trombones", etc.).
Louis Armstrong had a huge hit with "Hello Dolly".
Blues singer Junior Parker recorded both "Taxman" and "Tomorrow Never Knows"
The 1960s had lots of jazz performers playing tunes from the Beatles, Motown, etc. All of the American Songbook standards we worship today were just pop tunes from movies and Broadway shows. During the Swing Era for every Count Basie and Duke Ellington, there were dozens of non-jazz big bands like Guy Lombardo, Glenn Miller, etc.
Nothing's really changed the way I see it.
