With both a mutual friend and careers in the same field, Billy Corgan may actually be enough of an authority that his comments on John Mayer destroying his own career may be worth listening to.

Corgan said Mayer, whose recent interviews have been highly controversial, is doing something the former Smashing Pumpkins frontman is very familiar with. From the Rolling Stone article:

“He’s trying to destroy his career,” Corgan told Rolling Stone’s Brian Hiatt in an interview outtake from RS’ revealing new Corgan feature in the new issue, on sale now. “Rather than take a year off or change his musical direction … some part of it is irritating his soul to the point where he’s trying to blow it up. Certainly a talented guy, but empathetically, standing on the sidelines, it’s hard to watch someone literally burn their career to the ground — speaking as somebody who’s done it.”

Corgan was also none too happy with Mayer’s comments about Jessica Simpson, with whom Corgan claims a close relationship. Mayer called her “sexual napalm”, to which Corgan replied: “I think for any person who has celebrity to sort of drop rocks at somebody else’s feet like that — there’s things you should really just keep your mouths shut on. There’s things that should just be left alone.”
