Canadian Super Group Plagiarism?

The two greatest active Canadian bands (sorry Arcade Fire) have songs that sound awfully alike. The new Broken Social Scene album, which I love way more than any reviewer I’ve noticed, has a song in it called “Meet me in the Basement”. I like the song a lot, but it sounded awfully familiar to me. I was listening to The New Pornographers’ album “Twin Cinema” today, an album I haven’t really given much thought to even though it’s also very good, and the title track has an almost identical hook to the previously mentioned BSS track. The rhythm is the same, the speed is the same, and the key is the same. The result is the same exact notes being played at the same exact time. It’s almost a little too obvious.
