Lord Have Mercy
System of a Down's closing track had no real name for 25 years — just a guess based on a guest musician's first name.
System of a Down's Toxicity came out September 4, 2001. It debuted at No. 1, sold 220,000 copies in its first week, and had "Chop Suey!" already climbing rock radio. A week later the world changed, and that same song — one line in it, "I don't think you trust in my self-righteous suicide" — ended up on Clear Channel's internal list of songs stations were told to think twice about playing. It came off the air within days, per Consequence's look back at the album this week, timed to its 25th-anniversary reissue.
Track 15 never had that problem, because nobody knew it was there. It's an unlisted coda stitched onto the end of "Aerials," three extra minutes with no title printed anywhere on the CD. It features an Armenian multi-instrumentalist named Arto Tunçboyacıyan, so for 25 years that's what fans called it — not a real title, just the only name anyone had to hang on it.

The real title is "Der Voghormia." Lord, have mercy. A real Armenian Apostolic hymn. All four members of System of a Down are of Armenian descent, and per the band's own reissue notes, they perform this one live specifically to remember the 1.5 million people killed in the Armenian Genocide of 1915. It had been sitting there, correctly performed and incorrectly named, on a platinum record, while a very different eight words two tracks earlier got treated like a national emergency.
The reissue finally prints the real title in the booklet. Ships in November, on a run of 2,500.
