Deletion of Music Hour (Porno Graffitti song)

Comment: The Japanese wikipedia article :ja:ミュージック・アワー states that the song peaked at #5 on the Oricon Singles Chart and stayed for 22 weeks. It also says that it went platinum and was featured in a Pocari Sweat commercial. The same article has some other information that could be added to this. This may be enough to pass , but references are needed to confirm all this. Unfortunately the Oricon online database doesn't go back that far, neither does that of Record Industry Association of Japan http://www.riaj.or.jp/data/others/gold/. Perhaps someone else knows better sources
