Anna Kendrick (b. 1985) performed the cup song in Pitch Perfect (2012) and released it as a single in 2013, where it reached No. 6 on the Billboard Hot 100 — her first top-10 hit. She found the song through the same viral videos everyone else did, and never claimed to have written it; the misattribution is the audience’s, not hers. Her version is simply so famous that it buried the two layers of history beneath it.
