Normally in one year I have trouble coming up with just one album that really blew me off me feet, last year was PT - FoaBP, 2006 actually not one album managed to do that, but in 2008 I already had 3 contestants (Daylight Dies, Textures and In Mourning) and now the new Coldplay has REALLY grown on me as well, what a great album! That's already 4 fantastic albums in 2008 and we're only just halfway with several potentially great albums still to come out (Bloodbath, Anathema and yes, Metallica).
Mostly somehow the odd years produce more great albums for me, but 2008 seems to be the big exception now.
