Billy Corgan was out here slagging off Eddie Vedder in last week’s infamous “top two scribes” interview, and he continued his Pearl Jam diss campaign during a visit to The Howard Stern Show this morning to promote the Smashing Pumpkins’ new Monuments To An Elegy. Noting that he loves competition and hates the friendliness of alternative rock, he reiterated that Nirvana and Smashing Pumpkins were in their own class among ’90s alt-rockers and dismissed Pearl Jam as derivative. “I don’t think they have the songs. I think you stack my songs up, Cobain’s songs up, and that band’s songs, they just don’t have the songs.” He ceded that PJ have gotten it done as an arena rock behemoth for a long time and that he “has to bow to them” for that, but said he’s still confused about why they’re so successful. Here’s that clip:

Corgan also said he’s “not particularly” thrilled with Dave Grohl’s output with Foo Fighters. “My criticism of the Foo Fighters if I’m being a music critic is they just haven’t evolved, and that’s been the recent rap on them is just making the same music.” Again, he acknowledged that Grohl is “getting it done” and that from a career perspective, “he’s winning.” Here’s that clip:

He also talked about how he met Courtney Love, with whom he buried the hatchet recently:
