"A great way to write is to overwrite. Write more verses than could be contained in a song. Then take the best of what's there," says Rostam Batmanglij. I cannot agree more: good writers know that the first pass is never the time to decide what to keep and what to leave out. Overwriting will always be faster. Just ask Anne Lamott.

Of course, overwriting for Rostam comes easy because when he's not writing, he's thinking about writing. "I'm always collecting building blocks," he says. "Lots of kernels all the time. I've never truly let go of an idea."

Rostam's latest album is American Stories.

"When I'm not self-conscious, I tend to write better stuff. I need the dud sessions before I make progress," says Emma Jansson of Girl Scout. Good writing in the initial stages is indeed all about getting out of your own way and applying the Anne Lamott method. And it's why Jansson often starts her writing process with a pen and paper instead of a keyboard because, as she explains, "I don't edit as much when I use pen and paper. I respect the initial thought more."

Girl Scout's debut album Brink is out now.

"We should see how many disco records were made in the winter," Kevin Drew of Broken Social Scene said. And with that, we ventured into the intersection of songwriting and meteorology: how weather patterns and temperature affect the creative mind.

The Canadian songwriters I've interviewed tend to be seasonal writers. Many tend to write more during the winter, when they're likely to be holed up inside. Drew and I even dared start a new east coast vs. west coast feud as we pondered whether east coast writers are more productive because their seasons are more defined. But regardless of location, Drew says morning is his best time for writing because "it's one of your best chances to be free."

The latest Broken Social Scene album is Remember the Humans on Arts & Crafts Records.
