Tears for Fears and Peter Gabriel are among my favourite artists. I maybe like two Genesis songs. Of course no algorithm is going to be perfect though due to the emotional involvement we have with music, the people we identify with and age probably factors in to it a lot too. For example If I type in Tears for Fears it displays a lot of artists that I would have liked when I was younger but not so much today.
I suspect you are of a younger generation that am I. For those of us who grew up listening to Peter Gabriel's Genesis, the band's descent started when he left the band. Still, Second's Out, ATOTT, and Wind were great albums. When Hackett left the band, the remaining members should have just come up with a new band name. The are two bands who called themselves Genesis, and they even had some common members, but they were two very, very different bands, a sort of dualism. There are other bands who evolved (devolved?) in this manner, eg., Fleetwood Mac.
This perspective is a long-winded way of stating that for me, and I suspect most Peter Gabriel led Genesis fans, there's just no way that Oingo Boingo and The Police/Sting should be closer to Peter Gabriel than Genesis. I surely don't expect a perfect algorithm, but I would have hoped for a better one than this.
