From @Pepsi on twitter on August 1st, "We're working on fixing the wii tokens... Thank you for your patience and understanding!"
So, nothing new, but they still say they are working on it. I'm wondering if they aren't trying to get Nintendo to update the store to allow for download codes that specify a specific item, or song in this case. Or does Nintendo even need to do anything? It seems like they could do this already - I got a download code for the Wii Speak Channel with the Animal Crossing City Folk bundle, and it only allowed for downloading that specific channel, though that was a channel and not add-on content. Maybe that is where the issue lay, and perhaps they are trying to get Nintendo to fix that? Who knows. I'll be happy with tracks, but if we get points, all the better.
