David Benoit fared a lot better, Neneh Cherry matched Carmel(?) but not Youssou N'Dour with whom she had her most popular song. Interesting concept though I will definitely be playing around with it.
Edit: long ago I did something like this but based on the individual band members so that you could trace them as they moved through their career, that might be another interesting angle to pursue as a weight on the links. But it's a boatload of work to track down all of the individuals that contributed to a track. Another angle is to go by producers and possibly even recording technician. Good luck untangling Alan Parsons and Trevor Horn from everything they touched, the page will be too crowded to read.
