I have one song that I never knew for years that I got about 1997 on a replacement cassette from Woolworths titled The Best Of Dance. I remember asking this on Yahoo Questions And Answers and they didn't get it right as they thought it was a 1980s song called SOS Band - Even When You Sleep I was on about. I then came across shazam and it came up straight away with the right answer. The song is really called Coldcut - Dreamer from 1993 but it only charted at number 54 in the UK charts.
