The Wilhelmus van Nassouwe dates to around 1572 and is recognised as one of the oldest national anthems in the world, officially adopted by the Netherlands in 1932. It honours William of Orange and is normally performed at state events, royal occasions and Dutch sporting fixtures. The bass boosted version comes from online meme editing culture, where boosting the low frequencies of anthems, songs and speeches became a shorthand for mock grandeur. Shared on soundboards and in short videos, this take keeps that ironic use alive.
