Is this exactly the same as their Warm Snow mini-album, just with a new title and major distribution?

Per Japanese Wikipedia (Google Translate):
"Dwellers of a Sandcastle is a re-recording of the album Warm Snow, released after the album sold out, with a limited run of 30,000 copies. Compared to Warm Snow, there are some changes to the lyrics of Forest, but no changes have been made other than the re-recording and the arranger."

You can listen to the Warm Snow mini-album here, and yes it's different.

Edit: Playlist link keeps broken somehow, so here's Forest

Thanks! In the case, we should make each of these songs unique, as they're technically rerecordings and should show up differently in the songs tab.
