From Premiere Prep:
Linkin Park have shared another unreleased track from the Meteora box set, due out on April 7th.
The song is called "Fighting Myself", and Mike Shinoda describes it as “a definitive Linkin Park track." But it took a little more work to polish off than "Lost." Shinoda found the instrumental track in the band's vaults along with some vocal stems he and Chester Bennington had recorded more than 20 years ago. He assembled the various pieces to make what is essentially a new song.
