I think I would like this article a lot more if it wasn't making such a huge claim about the song's influence - it's great to see the effort that went into this, and I appreciate the breakdown of the songs that sampled it. But most influential feels like a bit of a stretch (or, more likely, editorializing). I mean, I think I would much sooner accept (or, who knows, even make) an argument that Crank That Soulja Boy is the most influential song of the century than accept that this one is. EDIT: And if we are going by "number of times sampled", then these have it beat by a long shot.
I like it when people break down music and give their opinions. It's nearly always entertaining, whether you like the music, agree with the points made or not. That's why I love Song Exploder - even when the music isn't my cup of tea - it's always a joy to get the musician's take on what goes into a song.
