I originally submitted Schwerkraft with BOF permissions, but it turns out all ROKINA songs are permitted for non-commercial use. From the webpage: "各作品は、非商用に限り、ゲーム・動画・アレンジ等自由に利用できます。"

It's required that if the artist name is specified in the webpage, the song should be credited as such. For example, $trange Attraktor should be credited as schwarzekugel, not ROKINA.
