If you have Played Battlefield Play4Free you have problaly heard the song "Age of Rage" by Corroded. But these Swede's are Epic. Underrated. I highly reccomend you checking them out.
Fun fact: Norway, Sweden & Finland have more Metal bands per citizen than any other place in the World.

Swedish metal is for the most part been incredible in my eyes and definately deserve more credit, I would recommend trying to find "days of jupiter" there are unsigned as of now but there may be something somewhere online but the album is some of the best i've ever heard.
