Metallica is way over rated today. Back in their hayday, the first 4 albums, unstoppable great metal. These guys should have packed it in when Cliff died or at least after their "and Justice for All" release. Don't know what people see in them today ? Slayer has gone from strength to strength as far as metal goes, still under rated.
Don't know how anyone could say Pink Floyd is over rated ??!! Wish You Were Here, Dark Side of the Moon, Animals... flawless masterpieces, timeless. My favorite band.
... Black Sabbath, Led Zeppelin were pioneers = brilliant stuff. Don't see how anyone can say they are over rated either. The 70s overall was the Renaissance for most of today's music.
