Would anyone happen to have the OST for POTC Dead Man's Chest and/or the back to the future osts? Looked everywhere and can't find them.

Go here: http://laleyendadeost.activeboard.com/
and register. Then navigate Specials / Especiales -> Pirates of the Caribbean.

I'm not sure if they have Back To The Future, you'll have to search for yourself. Try By Genre / Por G�neros -> Sci-Fi / Ciencia Ficci�n.

Hope you find what you're looking for :)
