I only bothered with the 80s and 90s ones but I can disagree with the 90s one from a UK perspective. Marky Mark Wahlberg's 'Good Vibrations' is not a big enough record to be in any 90s Top 10: that's only been put in there because of the fact he went on to bigger and better things and it's a good one to talk about because of that!
The Source ft. Candi Staton's 'You Got The Love' was out in 1991 too and considering that had a big revival in 1997 as well would possibly have more justification to be in a Top 10 list than Marky Mark!
The Real McCoy track 'Run Away' doesn't deserve to be in there either - 'Another Night' was their really popular one here and again I don't think that one would really deserve to be in a Top 10 either.
00s countdown was crap , there were so many better songs than those , completely biased... Top 10 IMO , that countdown should be renamed the Top 10 most popular songs of the 2000s
