"Yoshimi Battles the Pink Robots" is a song by The Flaming Lips
Lead singer Wayne Coyne says the inspiration for the song came from a woman named Yoshimi who played with The Boredoms. He had a recording of her screaming that he thought sounded like a fight.
The Boredoms were a Japanese noise-rock group from the early Nineties, with roots in the experiments of artists like Sonic Youth. They gained a small following and even played at the famous Lollapalooza festival, which showcased most major alternative rock acts of the day.
The screaming on Part 2 is actually the voice of Yoshimi.
The band made sure to include Yoshimi's real name in the title so that the listener would picture "a crazy Japanese woman" and thought that would come across with the name.
On the album, these songs appear as two separate, back-to-back tracks.
A video of this song appears as a special feature on a DVD of the TV show Friends. Instead of "Yoshimi," they change the lyric to "Phoebe," who is a character on the show. The video intercuts scenes of the show with Lisa Kudrow (playing Phoebe).
