4. The Roots - "The Next Movement": Ok, I really can't get on Mudge for not placing The Roots on his countdown since they are still tiptoeing the line between underground and mainstream. That being said the Philadelphia group is highly underappreciated and extremely different than most thanks to the fact that they are a complete instrumental group relying more on ?uestlove's drumming skills and Kamal's keyboarding over the typical sound of two turntables. I believe this song was released around 1998 with the video coming in 1999 and both are well ahead of their time.
If you've never heard the Roots, you should listen. I think you'll like.
