As of 2007, Candle in the Wind '97 by Elton John is the biggest selling CD single in world history

http://en.wikipedia.org/wiki/Candle_in_the_Wind

In Canada, it set a record for the longest chart single ever.  On the SoundScan Singles Sales Chart, it was consecutively in the Top 40 for over 3 years, spending a total of 45 weeks at #1 (35 weeks of which were consecutive).  The logic behind this is that CD singles are not sold in all Canadian stores, so ideally a song can chart in the Top 20 based on only 100 singles sold Canada-wide in one week. 

Since the SoundScan charts are not archived on-line, I scowered the net, eventually finding Top 10 listings, so at long last, here is the complete Top 10 chart run in Canada for Candle in the Wind '97 by Elton John ...
