I told you why I believe it's strange just in the quote...
There is ZERO trace on the internet about that album - weird for an official release, innit?. Absolutely nothing. Nobody else apparently owns this disc on any websites but have dozens of their other albums, and as soon as you add "13" to the many search strings I tried, it turns from "Oh, yes Orange Power 1-12 and Sound Giants and whatnot" to "Orange Power super cleaner and hearing aid batterie 12-packs" with 0% relation to the actual Orange Power music band. You open a webpage - even Japanese ones - and you browse through all the familiar Orange Power albums. Except for the elusive 13th. Also, just to add a bit more spice, having it is an AAC is also a rare thing - a lossy codec you gotta pay for due to the Fraunhofer royalty fee.
This music exists obviously, but I still wonder if they didn't market it as ORANGE POWER (label) and rather not market it under that name due to the circumstances. I would be happy to be corrected ASAP or in future though as there are two tracks which are bangers! But without credible data I can't add them to my database.
