This is an interesting mix of some classic melodic thrashy death metal with rrrreggaeton!
Children of Bodom – Bodom Beach Terror
Daddy Yankee feat. Miguelito – Al Son Del Boom (El Heredero)

Note that this is still a work in progress, just created it and looking for feedback on how it fits together, but most importantly how to mix/eq to bring out the parts better (so far my only real edits besides slicing have been a volume envelope that changes throughout the song). But its definitely 90% there — a ‘rough cut’, since most of the actual mashing is done.
Another thought would be to redo the mashup using the acapella of Al Son Del Boom, but I think the drums are already minimal enough to work, and in certain parts they add a lot to the song. And it would be a huge pain in the arse.
Please let me know what you think! Can’t get better otherwise…Al Son del Bodom Beach Boom
