Rivers Cuomo wrote a computer formula to help him compose new Weezer album

ABC/Randy HolmesWhen Rivers Cuomo began work on Weezer‘s new album Pacific Daydream, he decided to dive back into thousands of riffs, beats and ideas he had stored in his computer, some of which date back to the year 2000. To help him with that task, he wrote a custom formula in Google Sheets to help organize those musical ideas by key and tempo.

“Then I can see which ideas are most likely to fit with each other,” Cuomo tells Rolling Stone. “I’ll find an idea and be like ‘Whoa! I don’t even remember making this!’ It’s kind of like collaborating with myself.”

Technology has become a bigger part of Weezer’s recording process as of late.  As with last year’s White Album, the band didn’t record any of Pacific Daydream in the studio together, an approach Cuomo calls “completely unrecognizable from what I grew up with.”

“Things have been evolving this way for years, now,” he adds.

While Pacific Daydream came together thanks in part to computer formulas and solitary recording, the result is a batch of warm, summery songs like “Beach Boys” and the lead single “Feels Like Summer.”

“There’s always a part of me that just loves super-joyous pop music,” Cuomo says. “I just get so excited when [Carly Rae Jepsen‘s] ‘Call Me Maybe’ comes on.”

He adds, “It’s hard for me to be divisive in a song.”

Pacific Daydream will be released October 27.
