Looking at this list I realise that 2011 was a better metal year than I remembered it to be. Interesting year with a lot of surprises. The Shining album is in my opinion awesome, one of their best. Power Quest released their best album since "Wings of Forever". Amon Amarth keep on surprising me with solid releases (and I thought I was over them years ago). Opeth's "Heritage" was way better than my expectations. Amebix gave me some of the best tracks of '11. Overall, a really good year.

1.Shining - VII - Född Förlorare

2.Lifelover - Sjukdom

3.Aquilus - Griseus

4.An Autumn For Crippled Children - Everything

5.Öxxö Xööx - Rëvëürt
