Coming from iTunes on Mojave, the Music app in Monterey is absolute hot garbage -- it's the clearest example of how bad some native Apple software can be. Everything is very slow to load, there are tons of visual glitches, the cursor doesn't show the correct pointer when hovering over clickable content, etc. It's very obvious it's one of those iPad apps Apple ports to macOS like some of the other apps on macOS. It just makes them look cheap, like they can't be bothered to invest some time/money into a decent desktop app because porting the iPad version is easier.
