Metallica frontman James Hetfield HAS ALWAYS been a huge Raiders fan -- and he says he is still a bit pissed off that the RAIDERS moved to Las Vegas.
JAMES actively campaigned for the Raiders to stay in the Bay Area -- and supported local efforts to build a new stadium.
THEN the team owner got league approval to move the team to Las Vegas. The team is expected to relocate in 2019.
Hetfield says he'll continue to support the Silver and Black (he stuck by them during the L.A. years) ... but it's clear he's still NOT HAPPY ABOUT THIS.
