I gotta say I'm surprised that more people don't like Silver Rainbow on here. I'm personally not a huge fan of it myself, but in other past forums (that have long since closed down sadly), I would hear fans gush over how great of a song it is-and I was the one thinking it was overrated LOL!
At the end of the day, it's all personal preference I suppose. For example-It's Gonna Get Better (though seemingly forgotten by many fans) is actually one of my favorite Genesis songs!
