Best Ideas for Linkin Park's 7th Studio Album

It might be a long time away, but what would we love to see on the follow up to The Hunting Party? It will be a highly anticipated release, so let's discuss what us LP fans would like to see on their seventh studio album.
The Top Ten
1 Return to nu metal

Though The Hunting Party was much heavier than their last couple of albums, it still isn't nu metal. There is a difference between the nu metal sound of their first two studio albums (and the demos surrounding them) and simply being heavier. It would be a dream come true if they could make a true follow up to Meteora.

This list is so true. Yes, one more light was pop, but in an interview Mike said Chester wanted to come back to metal. Mark Morton, lamb of god's guitarist, did a song with Chester and said the same thing. So most of the list items would have probably fitted their eight album.
Unfortunately, things went in a different way😔

2 Experimentation

Failing returning to their roots, experimentation would be the next best thing, to release something truly unique. However, what they could experiment with next is up for suggestion.

3 More emotion
4 Even more atmosphere
5 Higher number of long songs
6 A concept album

Green Day did it and succeeded. Why not Linkin Park?

7 A much longer album than previous releases
8 More Mike
9 More guest vocalists / collaboration
10 More ballads
