I have spent a week straight trying to find a place to obtain the Oban Star-Racers OST. Thus far the only place that I found was the official shop/store. Can someone please help me find this? Thanks in advance.

couldn't find it

Blast.

I'd greatly appreciate it if this were found, too...
The closest I've gotten to date is the internetional opening theme, A Chance to Shine by Akino...

Even just a full version of the ending theme, "Goodbye Yesterday/Waratteta" by Mou Sukoshi would great if someone can find and share that, please... ^^
