I think that may take a while. As others have said, Seattle isn't necessarily a country music town. But this isn't traditional country music. Seattle people like to have fun, and this is music for having fun. It's also music that focuses on lyrics. That's missing from some other formats.
They key will be the morning show. Fitz was very successful at the Wolf. He really hasn't been replaced. But Tim & crew have a unique style that might work in Seattle. Tim's a big family guy, and people identify with that. He's a joiner and a volunteer. He does a lot of charity work. So he may meet people who don't listen while he's out in the community. That's what will make the difference. Outreach.
