How can you REMOVE a genre on a track that it clearly doesn't belong in?

I discovered that Soundcloud now has charts and of course immediately checked out my favorite genre. To my horror, it contains many tracks that clearly don't belong in this category. For example Dr. Peacock = Frenchcore Worldwide (see the song I highlighted in the screenshot). In the title it even says that its Frenchcore. And if that genre is too narrow for you then it could perhaps fit in something like 'hardcore' (I'm not very familiar with the harder styles, so no offense to any Frenchcore fans).
Would it be possible to help categorize tracks in the genres they belong to? I' m sure that people would be glad to help out with this.
