Chocolate Rain
The song and video Tay Zonday posted in 2007, where the contrast between a young man and an unexpectedly deep bass voice made him one of YouTube's first real phenomena.
Its spread was driven by two things that had nothing to do with the music. The first was the voice, which did not match the person in front of the camera at all. The second was the caption "I move away from the mic to breathe in", explaining why he turned aside between lines and becoming the thing that actually got quoted. The joke belonged to the whole world and the remixes were endless. Zonday has consistently pointed out that the song is genuinely about structural racism, which essentially nobody spreading it cared about — an early and clear example of the internet choosing its own reading of a work. He has said he is content with how it went.
