Smashing Pumpkins frontman Billy Corgan has been talking trash about just everyone in music this year, and now beloved grunge goliaths Soundgarden are no exception.

Corgan, who has presided over several incarnations of his band he's led since 1988, shared his thoughts on Soundgarden during a recent interview with PhilStar.com. After lamenting the rise of 'American Idol' wannabes with "no respect for the tradition of music," Corgan was asked for his thoughts on the return of bands he shared the charts with during the Smashing Pumpkins' early years.

"There are those bands that are essentially coming back only to make money," he observed. "Playing their old albums, and maybe somewhere in the back of their minds they’re thinking there might be a future. I am not in that business, obviously."

Corgan focused specifically on the Soundgarden reunion, saying, "When Soundgarden came back and they just played their old songs, great. I was a fan of Soundgarden, but call it for what it is. They’re just out there to have one more round at the till; same with Pavement and these other bands."

So what makes Smashing Pumpkins different from the rest? "You have to make music for 2012," Corgan argued. "Without the young fans there is no future for Smashing Pumpkins. We can’t run an oldies business. Not only is it boring, it’s actually not a very good business."

That all said, Corgan may not be aware that Soundgarden are indeed working on a new album that should be released this fall. They've already scored a No. 1 rock hit this year with 'Live to Rise' off the 'Avengers' soundtrack.
