Unfortunately, one of my favorite AMVs in a long time is no longer on Youtube. You can find it here on AnimeMusicVideos.org. It’s responsible for getting me into Puella Magi Madoka Magica. You should definitely check it out.
This next one probably can only be viewed on Youtube proper. It uses video from ef – A Tale of Memories, a show that I’ve been meaning to watch. This video has definitely pushed it higher on my list.
