So this comes a little bit late, but I might as well throw it out there - Anime Remix added a new song the other day, an old little sample-remix called "Totoro's Groove" by po! It's a goofy little groove with a chopped up sample from that fun old Ghibli movie, "My Neighbor Totoro". Not a totally complex or amazing remix, but it sounds pretty cool anyway.
What's more fun about this remix is what it signals for Anime Remix, which is that straight-up remixes - not just rearrangements - are now fair game for the site. Anime Remix, which has been hosting rearrangements of anime songs since 2002, made a decision that, legally, straight-up remixes weren't any less of a gray area than rearrangements, so catchy little songs like "Totoro's Groove" are just the beginning of what's possible.
