Blue Monday by New OrderAUG 25 2004
Thanks to 24 Hour Party People, I'm discovering New Wave, albeit about 20 years late. From 1983, here's the original UK release version of New Order's Blue Monday (mp3, 10.2 MB), the best selling 12" single of all time.

If you like that, you'll want to get your hands on Substance: 1987, a compilation of their post-Joy Division early singles from the mid-80s. There are other New Order greatest hits comps out there, but that double CD was the first, and is still the best. It stops right before the point where they went a bit shit.
