Here are some hints for the next five:
#49 is the first of many slabs of female-fronted awesomeness to grace the Sexy Sixty this year.
#48 is a very similar album to one I just reviewed, except that it was released by Profound Lore and not Translation Loss.
#47 is the first of the plethora of old-school death metal albums released in 2011 to crack the Sexy Sixty.
#46 is a sludge / doom album by a band that I've been trying to like for a while now, and this year's release finally did it for me.
#45 is another doom album, by a band that I had never heard of before last year, and whom I'm really sorry I missed on tour in 2011.
2/24 Russian Circles/KEN Mode/InterArma
3/25 or 3/26 The Ocean
4/24 Behemoth OR 4/26 IntrOnaut/Cloudkicker (?)
