Why does an album have to be "the best" and so on and so forth?
Het is inderdaad raar om een "beste CD" te kiezen.
Mensen hebben nou eenmaal behoefte aan lijstjes en rangordes... Puts your mind at ease
But somehow this album surprised me the most with its diversity.
Good way to put it. Though really, you're saying, this album was best in the 'diversity' department. Perhaps another album was mastered better, and yet another one was the most emotional. It seems diversity is the aspect that appeals to you most, so in a way, the Joanna Syze album was 2011's best - for you. At the same time, Hidden and addiQted are right - there are infite ways to enjoy music, infite aspects to be considered 'the best'. So when viewed on a larger scale, no single album or release can objectively be seen as superior to all others.
Of course, it could be argued that when you give an album a mark for all of its merits - diversity, mastering, emotional impact, and so forth - the one with the highest average is the objective best. However, as addiQted said, this varies from person to person and even from time to time. Meaning, ultimately, how 'good' an album is is far from a constant, and all there is to it is just to enjoy what you like, personally.
