"There was never any bad blood between us," Cornell said. "I've always remained on great terms with everyone in the band. We've always been good friends. Seeing them reunite recently on YouTube? I thought that was terrific. It gave me a warm feeling. I wish I could have been there."
Putting a fine point on the likelihood of reuniting with his former bandmates, Cornel said matter-of-factly, "I'm never going to count anything out."

Three quarters of Soundgarden - guitarist Kim Thayil, bassist Ben Shepherd and drummer Matt Cameron - reunited at a recent Seattle show to play three of the band's songs with local grunge icon Tad Doyle. (See fan-filmed video footage below.)
Cornell himself has been on the road in support of his latest solo album, "Scream", which has been blasted by critics and fans for ditching hard rock in favor of an electronic R&b style.
Asked whether he was "stung" by the reactions to the record, Cornell recently told the Washington Post, "I would be stupid to assume that (all my fans) would like it. I would be stupid to think that everybody would, like, get into something that's really sort of an electronic rock record. In terms of its instrumentation, it's entirely different than what they're used to or what they might even ever want to hear. It doesn't sting at all."
Cornell also remarked on the album being slammed on Twitter by Nine Inch Nails frontman Trent Reznor, calling the idea of doing that "childish." He added, "To be honest, if I wanted to go out to blast records that I hate, I would be sitting on Twitter 24 hours a day blasting 96 percent of what comes out . . . There's a lot of music that I don't like."
