I hate it when people put their PERSONAL views of certain songs or artists over being objective about that song or entertainers legacy. MJStan said it best for me. You can argue who has the greater legacy but don't let stanwars take it to the point where you won't give an artist who is NOT your fave credit for what they have done in the industry.

But I will put it like this: If your fave artist is on say, the Top 20 Decade End Airplay List then most likely they have songs that will numerous songs that will be remembered from that decade, depending on the format: http://www.billboard.com/charts-decade-end#/charts-decade-end/radio-songs-artists?year=2009
