You check my list out yet? I think this tune could metal pretty good. A little quicker, 16th note double kick and chugga-chugga guitar instead of the reggae-synth up beats. Heavy guitars playing the steel drum counterpoint. Metal up the voice but keep the melody. Would fuck shit up!

to achieve more attention, always aim for songs from another genre which no one would expect to hear in the style of heavy metal

Make drone doom metal from Queens of the Stone Age songs and I'd listen to that stuff 24/7
