Question: what is the biggest selling 12 inch single of all time?
Answer: On March 7th, 1983, New Order pioneered dance music with the release of the best selling 12 inch single of all time—Blue Monday, whose initial run sold over 700,000 copies. The song (now used to name the depressing 3rd Monday of January) is perhaps the most acclaimed and even influential synth-pop track of all time.
