Linkin Park are pop now. With their last three tracks - “Heavy,’’ “Battle Symphony’’ and “Good Goodbye’’ - they are one step closer to becoming an all-out boyband. Even for a band who are hated by a significant portion of metal circles, the new tracks have incurred the wrath and mockery of haters and fans alike. But it’s not that much of a grand departure either; Linkin Park has always been rooted in pop music to an extent. When they arrived on the scene during the apex of nu-metal, they brought a polished shine to the genre that was much more accessible than that of their peers. Hybrid Theory was a groundbreaking album in many ways, but it lacked the abrasiveness of Limp Bizkit and Korn records, offering a squeaky clean alternative to many of their peers. While pop elements can be found in the music of most popular nu-metal bands from the genre’s heyday, Linkin Park embraced them more on a grander scale from the get go.
