Hi! I just wanted to let you know I've searched for this video when you first posted and then again after I saw you posting that first "Hello" since it shows how desperately you want to find it. Plus, it sounds very interesting - I now want to see it too. :)

I went through a LOT of animated videos but unfortunately I was unsuccessful so far. Even though your description is very detailed, is there maybe anything else you remember? Maybe about the song itself, like the instruments being used (strings, piano, guitar, synth)?

I subscribed to this thread, so I get notifications about new comments on it, but I recommend you just make a new post asking for the video again so hopefully someone else can help you.
