First, god bless you for what you are doing on this site. :-)
Song "Alfonsina y del mar" has a formatting error – some of the chords are in the same font as words and therefore they are not getting transponded when one request so (I believe this is how this is working?).
Also, it looks that some of the chords need improvement.
BTW, what kind of chord would be “Eminv”?
