Ive included some death metal (Amon Amarth & Decapitated) to go with the new thrash metal that Ive found (Bonded By Blood & Toxic Holocaust). No list is complete without some speed metal as well (Exciter & Enforcer), as well as some Priest. Also put Jag Panzer in to cover some power metal and some DevilDriver for some metalcore.
I also didnt go with all classic or new albums either. In terms of time of release, although most of these have been released in the past year or two, there are still some classic albums worth listening to in there as well (Painkiller & Violent Revolution).
In my honest opinion the new Paragon album isnt quite as good as their last (Forgotten Prophecies), however its almost impossible to crank out another masterpiece after such a great album was released not so long ago.
Painkiller stands alone... if you havent heard it yet, make it your next listen.
