I am probably going to get hate mail for this, but check out the new album from Swedish group Hellsong called "Hymns in the key of 666".
They are a so called 'soft' or 'lounge' metal band and do acoustic/atmospheric covers of heavy metal classics (I can see the colour in Chris7's cheeks rising

). However, the results are surprisingly engaging.
It is available on Sparks if you are interested (and game to try something a little different).
