It has a column browser, located at the top of the interface, so it doesn’t block song info, unlike 3.5. It also doesn’t assume that, when the user clicks on another artist, in the browser, it means the user wishes to select both artists, unlike 3.5. This change, in 3.5, was obviously very cumbersome, when one has a large music library and wants to switch from, say Brian Eno to Thelonious Monk, or something along those lines. It is also very easy, when using 3.2, to select multiple artists/ albums, should one desire, by using the Command key, in MacOS.
Long story short, the only reason I abandoned 3.5 was that the UI was godawful and represented an unimaginable step backwards, in terms of functionality and user experience. After over a year of feeling like I was shouting into a void, trying to get responses to my many issues with the new software, I simply gave up and back-graded to 3.2.20, which I use [mostly] happily, to this day.
It makes up for what it lacks, in terms of sound, when compared with future releases, in basic functionality and overall user experience, especially if the user has a large, local music library, as I do.
Again, I just can’t imagine how someone looks at the most popular, widely used music library management and playback software on the planet and says “I’m going to design something that throws out both the good and the bad with this platform.” It just never ceases to boggle my mind.
