Well the video editing is really nice, and so are the drifts most of the time, surely a good video but the orange-background outro with the keyframing is really weird, although it's the limitation of the software as well. At least effort put into it.
As for the music, it's always the editor's taste/preference, if I gave a score or something I wouldn't give less "just cuz I don't like the music" - since it goes okay with the vid.
Personally it's like 7, but that's not what matters:
Technically (editing, content, a/v sync etc) it's around 9/10
Good job.
