What's the oldest hymn in common use?

[Polycarp]

Cool. Who regularly sings it and how do they know the tune? Has it just traditionally been passed on?

Jack Marti sings Moses’s Greatest Hit

[Chronos]

I’m pretty sure that often shows up in Easter Vigil masses (which are a big to-do, with 7 or 8 readings, and lasting 2-3 hours).

Actually, the oldest song still regularly sung from the Bible isn’t from Psalms- it’s the Song of the Sea from Exodus 15, which many researchers believe to be one of the most ancient passages in the Bible.

Does anyone have a cite for this?
