Hi Rob,
tl;dr:
Singlechart is excluded on purpose. Including it may make sense, and we
could probably even define a useful mapping for it (as an
IntermediateNodeMapping [3], to attach its data to the main resource for
the single).
If you want that to happen, feel free to file an issue :-) [4]

English Wikipedia has a template called "Singlechart" that is used on
many (~10 000) musical singles[1].
However, the DBpedia statistics page doesn't show any uses of this
template at all[2].
Is there something special about this template?
