Ooh, msconfig - a blast from the past! Thank you, @Paz. But Spotify wasn't in there, either.
It turns out there is a setting in the Spotify Settings menu to start with Windows Logon or not. It was set to Not, but it was starting anyway. I set it to start with windows and rebooted - it started, all right.
Then I set it to Not, and rebooted, and this time it "took". Spotify no longer starts with Windows.
