After discussion at WT:WikiProject Croatia and with a Croatian editor, Sveroh (see this and this), I've come to the conclusion that the reason this article isn't sourced is because the described chart doesn't exist. There are some individual station charts that approximate the description, but none of those warrants the title "Croatian Airplay Chart." It's not clear to me if the HR20 chart is an official chart or not, but even if it is, it probably isn't suitable for an article in English Wikipedia, as it documents only Croatian language singles.— Kww( talk) 16:26, 9 September 2009 (UTC) reply
