Here is the most and least played song live off each album by thrash's 'Big 4'Metallica, Slayer, Megadeth and Anthrax.

The Big 4 account for a total of 49 studio albums, with Megadeth being the most prolific at 16. It's a lot of material to consider when playing live, especially with so many all-time classic records between them. There are setlist staples that have dominated the decades and, of course, countless rarities, deep cuts, hidden gems... call 'em whichever you'd like.

Unfortunately, a lot of great songs from deep in each band's career are resigned to being played just on the supporting album tour. It's what keeps the diehards coming back, always hopeful to check off seeing another song for the first time or one that hasn't been played in a while.
