After past snubs that drove Black Sabbath lead singer Ozzy Osbourne to dismiss the Rock and Roll Hall of Fame vote as "totally irrelevant," the heavy-metal pioneers are finally on their way in, to be joined by Miles Davis, Lynyrd Skynyrd, the Sex Pistols and Blondie.

Ozzy's 1970s group was first nominated in 1996. But the hall has largely ignored metal since the organization was founded in 1987.

Davis, the late trumpeter, is the first jazz musician accepted as a full inductee. Louis Armstrong (1990), Dinah Washington (1993) and Billie Holiday (2000) were previously honored as being early influences on rock-and-roll.

The Sex Pistols imploded after only one album, but not until Johnny Rotten and Sid Vicious shocked the rock establishment. They inspired waves of imitators in spiky hair and torn clothes, but the rock hall was quicker to recognize peers the Clash, Elvis Costello, the Police and Talking Heads.

Blondie, with Deborah Harry as lead singer, was among the most commercially successful of first generation "new wave" bands with hits like "Heart of Glass" and "Rapture."

The induction of Southern rockers Lynyrd Skynyrd means that requests for "Free Bird" will never go unanswered at the rock hall.

The annual ceremony is scheduled for March 13 at the Waldorf-Astoria Hotel in New York.

Artists are eligible to be inducted into the Rock Hall after at least 25 years have passed since their first record was released.
