Canadians: you no longer have to jump through hoops (or hope for an early invitation) to check out Spotify. The streaming music service has finally launched in Canada, complete with an extensive collection of domestically-made tunes. As elsewhere, you can play songs for free if you're willing to put up with ads, and shelling out $10 CAD per month for Premium lets you stream without commercials. The service is definitely late to the party -- it's years behind Rdio, and even Google Play Music arrived a few months ago. Still, it's hard to object to having one more way to listen to Grimes or Leonard Cohen.
