This is really tough, I probably only bought about 15 new releases this year. In no particular order:
Mastodon - Blood Mountain
Tool - 10,000 Days
Winger - IV
Witch - Witch
Iron Maiden - A Matter Of Life And Death
As for oldies, I've been listening to all my usual stuff like Clutch, Tesla, Badlands, Rush, Trouble, Sabbath, Deep Purple, AC/DC, Robin Trower, Scorpions, Robben Ford, Thea Gilmore etc but I also rediscovered a few old vinyl favourites on CD:
Y&T - Mean Streak
Coney Hatch - Outa Hand
Sword - Metalized
And I always come back to these two:
Unida - Coping With The Urban Coyote
Circle Of Soul - Hands Of Faith
