Mine has to be Exist, it's from The Stage which is the 7th and latest studio album from the metal band Avenged Sevenfold released in 2016.
The song is 15 minutes and 37 seconds in length and it's a masterpiece.
Avenged Sevenfold are known for their vast array of long songs such as M.I.A, Sidewinder, Strength Of The World, The Stage, Save Me, A Little Piece Of Heaven and more.
Exist even has Neil deGrasse Tyson doing a 3 minute monolog at the end about space exploration.
