I was trying to figure out the top 20 groups or solo acts from August 1986

[Future Citizen of Forvik]

thru May 1990? My guess would include Guns N Roses, Motely Crue, Skid Row, Bon Jovi, Def Lepard, Whitesnake, Poison, Madonna, Aerosmith, Metallica, and Michael Jackson. After these guys I get sort of lost in the chaos of all of the one hit wonders of that era. Of course if I am wrong about one of the ones I chose then I am ready to hear why not. So there are at least 9 spots open. The ranking is not all that important and links to informative sites would be helpful.

Thanks.
