I love iTunes on my Mac. If they replace it with something else, it better be insanely great.
I too enjoy it. I'm actually a bit bothered that they got rid of iPhone app management from their latest builds, as being able to sort the home screen with a mouse is a lot more efficient than on the device itself.
Calling it bloated because it has Music, TV, and Podcasts just to then separate it into other apps is silly, IMO. Then you just have more applications.
The Music app had better come with a dark mode, and proper device management. Or just launch a separate device manager.
