This is very true. It does cross my mind sometimes when am making the best of lists. For example - you instantly fall in love with a Nov/Dec release and it makes its way up to your final top 3 or top 5 spot. Then as months go by you realize you don't love the melodies as much as you used to in the beginning and find yourself going back to albums that were released earlier in the year which eventually ended up way below than the Nov Dec release album in the best of list. It happens every year with one or two albums/songs. But as you mentioned, it is what it is.
To play it fair, we can have our lists out sometime in March but again, don't think no one has time to keep it on hold for that long.
