The online song listing has also been merged with the
Suppon site. Haven't really messed around with it too much to see what's new, but at the very least you can now listen to the radio shows online.
Also, the Splatoon theme is available as a free download from the Radio Shop. Seems there's a bunch of other stuff that's been added since I've last checked like Pikmin outfits, a free Captain Toad track, and GUMI music videos.
Every time I think the game is dead, a big update gets pushed out, lol. Pretty surprised that, despite being relatively unpopular, the game is still getting this level of support over a year and a half later.
anyways let's play sometime. for real. i mean it, dammit!
