I have four for the anime Rockman.EXE and four for Princess Tutu. Got ideas for two Full Metal Alchemist videos, and random others for Rockman and Tutu. :/ Also one for Hikaru no Go.
Been thinking of making one about Malice Mizer/Moi dix Mois, but I don't know how it would turn out/if I'd do any good at it. The probably would be finding enough/the right clips, since with Jrock, there's just interviews, PVs and lives, and there's always different. And with anime, you've got (mostly) the same style, if you're making the video with one show. So I feel it's easier to make one with anime than Jrock.
