Take it easy, man, there's no hurry at all. Glad you liked Unleashed.
I leave this for everyone's consideration. I'm in a Viking Metal band (that label is wrong, as they throw in bands with different styles just because they sing about Vikings) and we're considering covering a song that has nothing to do with the style, such as House of the Rising Sun by The Animals.
Do you like when a group makes a cover of a radically different style or you just plain think they destroy the original? I leave you an example in the form of Losing my Religion revised by melodic Black Metal band Graveworm:
