Is the Umineko ED used elsewhere? Recently, I have started watching Umineko no naku koro ni (When the Seagulls Cry) and I found the ending song (YouTube link) of this anime very familiar and similar to a song I have heard before in another anime. In particular, the part 0:40 - 1:00 sounds somewhat like something I've heard before. 

Now my question is: did the same singer perform for any other anime, or are there singers who sang the same song as he did (specifically, the part of the song at 0:40 - 1:00)?

Edit: From the comments, I know the song is not used in any other anime known to date.
This ending theme song is titled La Divina Tragedia: Ma Kyoku. It was recorded by Jimang. The song does not appear in any other anime. From the looks of it, Jimang has not had any other song appear in any anime. But one of his other tracks, Sakura POP, has been used in the Korean MMORPG, MapleStory.
