Taylor Swift sings whiny songs about bad boyfriends. Stevie Nicks made her boyfriend play guitar on songs where she sang about what an arsehole he was.
I think you have it backwards. What song are you referring to? I've never heard he was insulted by any of her songs, but she didn't like Go Your Own Way, and she had to sing on that. And she didn't "force" him to play on anything, he insisted on Fleetwood Mac taking her, if they wanted him.
