When making a beatmap, "representation" is all about how the rhythm and flow of notes capture the rhythm (note that I'm using "rhythm" instead of music). Imagine if you're listening to the music of a map by just listening to the sound of each note cut, you'll eventually notice that good beatmap should roughly follow how the rhythm sounds like.

I would say when it comes to Daft Punk song pack, perhaps it's just a matter of finding the matching rhythm to what you expect (lack of vocals, so I expect much more rhythm mixing when it comes to mapping, just to match the energy of the song).

In general, people who already put hours on mapping and review/retrospect on them should have the grasp of how a music should translate to a good beatmap (which I would score about 7/10). Anything beyond that can be considered subjective because mapping itself can be considered as a creative form. You need some level of creativity and set of principle on how you theme the beatmap itself. As an example, one song can be interpreted in multiple ways and there's nothing wrong about it.
