Who wrote the Bangles' song "Manic Monday"?

Yes, the lyrics are a bit cheesy, and everybody knows Saturday is the real fun day, but I'll accept whatever Prince says. "Manic Monday" was originally written for Apollonia 6 under his pseudonym, "Christopher," but he pulled the track and just let it sit there until he came across the video for the Bangles' "Hero Takes a Fall." He liked the group (specifically bandmate Susanna Hoffs, according to rumors) and the song so much that he performed it onstage with them. He prepared a mixtape for the group that included "Manic Monday," and after adding some Bangles magic to Prince's royal writing, they had a song that almost hit the top of the charts. It peaked at number two on the Billboard Hot 100, blocked by "Kiss" from... Prince. Yea, he's just that good.
