The overall hype for LT was WAAAAY bigger. Look put on youtube, for example! I remember to see all the old songs getting a lot of views, the hype was insane. Burn It Down lyrics had 15 million views before getting the music video. Minutes To Midnight, Meteora, HT, all these album were back on the top 200, and there were a lot of singles selling, I remember that on iTunes store on germany 8 out of the top 10 rock Songs were LP, and OLD songs. (This one week before LT come out) Releasing a top #1 album with a typical LP powerfull sound, with the influences of EDM, good hype, a big hit like BID... A lot of people were into LP again after 2 years or even more (LT would polarize less the fans compared to the 2010's ATS) One year later, RECHARGED. The band already forgot LT to go on a full EDM remix album. Again, some hype, some people getting tired of LP, of this electronic change, etc etc. Basically what happened was that they released 3 albums in 3 years. Plus, bad promotion, no real "lead single". People got tyred of having LP all time. If THP were released on the end of 2015 it would have more hype, and it would sell more.
