I was wondering if non-english language albums get an increased weighting to compensate for the language barrier which often prevents most of these artists from breaking through internationally? Sure English worded music has a significant advantage in this respect?

Good question. The answer is that non-English music have an alternative weighting, German lists are weighted higher for German-language music etc.

In addition, there could be some kind of "increased weighting" for non-English spoken music. But exactly how would this be justified? Anyone who disagrees with this suggestion?
