Among rock beefs this one is, perhaps, the perfect storm; two temperamental, faded rockers with giant egos, neither much for reason or logic, go at each other. They’d been friends -- at one point romantically linked -- for 15 years when, in spring 2010, Love released her solo album Nobody’s Daughter, which contained four songs co-written by Corgan, who complained to Rolling Stone that her use of these songs was unauthorized. Love issued a typically incoherent apology on Facebook but Corgan was evidently unmoved; he took to Twitter to rip into Love’s abilities as a parent and songwriter and take her to task for exploiting Kurt Cobain’s legacy.
