Hopefully it's something that Linkin Park wants to make themselves, even if it is poppy, and they don't give a fuck about what the 20 ''hardcore'' fans think on LPLive. I've been a member of a lot of fan sites for bands and this site talks the most shit about any band I've ever seen. Linkin Park has never been on a full on rock band and they probably don't want to kee making heavy music just to please the 20 or so people I see on this sit blast the band all this time.
If they want to go for a pop album, go for it. If they want to go for a metal album, go for it. If they want to go for a country album, go for it. If they want to go for an EDM album, go for it. It's the bands choice...
Personally, I think they will continue on after where they left off with Living Things. It seems like the band kind of went out on an edge for The Hunting Party since that wasn't their original direction in terms of progression but the band was so inspired to make something heavy that they went for it.
Mike did say during an interview at Rock In Rio that they were satisfied with the reaction they got from The Hunting Party and that they want to experiment on the next album, so that seems to me that they probably are pursuing a different idea than the kind of music made for a The Hunting Party.
I personally think some of their best work were on albums like Minutes To Midnight, A Thousand Suns and Living Things so I hope they can deliver with those caliber of songs again. Chester has a great voice and they don't utilize it enough in my opinion. Stone Temple Pilots utilizes it, so should Linkin Park. I also think they are really great at writing melodies and choruses that will stick in your head and I hope they write those kind of songs again.
