can someone help me find the last chests

[clamdove]

i have two problems. first, i've gone to every chest shown on the map (that hasnt already been opened) and only found artwork chests, but i have a song chest key and want to use it. secondly, the pause screen tells me i have 13 chests left to open, but i only see seven on the map
below are links to screenshots of my map, both of which were taken inside the doom zone. your help would be highly appreciated

The map chests only show up if you've gone near them before.

Use this video instead. Check the first comment and it tells you what is in every chest. If you go to the Collection Room, you can see what you are missing and can tell exactly which chest it is in.
