The Weakerthans -- the best band since The Smiths. There. I've said it. John K. Samson has this uncanny ability to use all of his influences-- lyric poetry, literary and Marxist theory, country, punk, etc.-- to craft intricate and beautiful pop songs. The band nails it every time. You can't go to a Weakerthans show and not be uplifted. They can be sappy, hyper-emotive, highly political and still rock like bastards. There's a generosity and fierce intelligence in their music that restores my faith. I strongly suggest you visit them here.
And while you're at it, visit John K. Samson's brilliant publishing house here.
