Life of Riley is a cheerful royalty-free tune by Kevin MacLeod that became familiar through countless online videos, where its bouncy piano melody often signalled light-hearted or wholesome moments. Meme editors later created bass-boosted, earrape versions that turned that innocent sound into a loud joke, using it in the same way as the Vine Boom and MLG Air Horn to punctuate a punchline or startle a viewer. Because the original tune is so recognisable, the distorted version still works today for pranks and short-form comedy, where the contrast between the happy melody and the harsh bass is the joke.
