The way application icons are rendered and displayed can vary a lot between display settings, screen resolutions, applications, the use of scaling, etc.
The current MusicBee icon file (musicbee.exe) contains a limited amount of the basic recommended icon sizes. These will work fine in most circumstances.
But when an application—or Windows scaling—needs to display an icon in a size that is not provided, it will do some resizing of an available image.
That will usually probably look fine, but it won't be pixel-perfect as intended.
Here are some MusicBee icon sets that contain pretty much all icon sizes that Windows and most applications will ever need.
I made three colour variations: the original MusicBee colouring, a green version, and a red one.



note:
I'm not using a 4k display, nor Windows scaling (125% / 150%) myself, so I would be interested if a forum member that uses one or both of these could provide feedback if it does make a noticeable difference.
I'd like to know if it's really worth the effort to create and include all these different sizes.

updated:There are now three sets of icons.
All icons are what I call hi-res, meaning that they contain pixel-perfect image sizes for all occurring situations, including 125% and 150% Windows scaling.
The first is a set of subtle colour variations on the original MusicBee icon. (row 1)
The second set uses more solid colours. (row 2)
And the third one contains outlined icons with transparency in various colours. (row 3)
