What's the name of the song that played in the last few minutes of episode 13 of Charlotte? It's towards the end of the episode, something about Sinking Ships but I can't find the song.
「君の文字」 Kimi no Moji "Your Glyphs", sung by Kumaki Anri. It ought to be out as part of the OST on 4 Nov 2015.

"Sinking Ships" is the one that starts at around 12:50 into the episode.
