It's very Hans Zimmer ish, but the chords aren't quite the same. Phrasing is pretty much copy/paste, but there is definitely a lot of creativity going on here too.
Lidallie As long as you give credit to the creator (not any video promoting the song, but the actual creator), you won't get in any sort of trouble. However, if this video is used in a marketing campaign and is making money, then you specifically have to ask the creator for permission. Otherwise, you can be sued and lost all money you made plus more ;) Be wise!
