"Include Me Out" by Young Marble Giants
I've gone through many phases with this band. When I first heard them, I was relatively inspired by their minimalist pop. Then I slowly started to find them quite boring. Then I went a good year or so without listening to them at all. And now I'm back where I started on account of their music truly being amazing. This song in particular is one of the defining pieces of post-punk, for me at least. The beat is kept by a Geiger counter, and there's a simple, repetitive, punk-y guitar riff on top. A bassline moves the tune forwards, and the vocals, delicate but purposeful, are catchy and complimentary.
