I believe they're both out of print, so you'll need to find them used. There are used copies of World's End Curtain Call available on Amazon. Amazon UK seems to have a significantly cheaper copy than Amazon US. I can't find a copy of Psycho Pop Candy Girl, but you might find it on a Japanese reseller site like Yahoo Japan auctions, surugaya, or similar - though you'll need a middleman service for that. Digital distribution of niche songs is very rare in Japan from everything I've experienced, and even where it exists it requires some complex use of proxies and Japanese verification, like valid ID information, so I think you'll be hard pressed to get official digital copies anywhere.
