In respect of ジャイロ(4th)P さんGame play video not equal to actual selling the music! 日本レコード協会!!May think about others such as ハイファイ☆デイズ if timing is good( thanks to some idiots)by the way, recommend to use jdownloader2 or niconico extractor for download (yep. to prevent some idiots from deleting again.....)
