Cons
Con It won't install on Linux Mint 21
Con Held back by performance issues
Can be very slow, uses a lot of resources, and has a decent amount of lag when going between songs.
Con Doesn't support media keys
Con Unusual keyboard shortcuts
Space does not pause, for instance. This would have been useful, as hitting the space bar is easier than finding the play/pause button - most music players use the space bar in this fashion.
Con Some plugins are outdated
Several plugins works on older versions of libraries no longer available for recent distros.

Con Poor library management
Initial load may have issue skipping parts of ones library, re-scanning may not resolved the issue. It also may tax ones CPU quite a lot, during these load attempts.
Con No WMA support
For those with older libraries that may still have unconverted WMA files, this can be a non-starter.
Con Large assortment of features and layouts may be confusing
Some people may find all of gmusicbrowsers layout and options daunting to figure out.
Con Unstable on Wayland
If you even attempt to resize the program, it'll hang indefinitely.
