I am look for a song (Duh) It a piano and string mix that was on one of those best epic or something song list for a month in 2013 I think a winter one. I found it as track number two on that list. The piano and strings would take turns and it was sad but fast tune. Parts of it remind me of movie computer hacking. The string and panio would switch off. It sound a bit like this at start but much faster and actiony with no vocals
