Music by John Williams

I discovered you can look at album credits when listening to music in iTunes.  I was listening to Star Wars The Force Awakens today....  I clicked on the credits and they said Gustavo Dudamel was the conductor in the credits for the album?  Really?  So I looked at the cover of the cd I own and it says Music by John Williams.  If you look at the first 6 Star Wars album covers they say Music Composed and Conducted by John Williams.  I wonder when John Williams stopped conducting on his albums.  TFA is copyrighted in 2015.  I checked the credits on Indiana Jones and the Dial of Destiny (2023) and conducting credit is shared by John Williams and William Ross.  The last three Star Wars movies just say Music by John Williams.  Solo a Star Wars Story(2018) give conducting credit to John Williams and Emlyn Singleton.
