I think you are on to something here Slackman, but if liking Boston albums is the worst side effect of the governments ploy's to sell razors, then I hope the radiation tests in phone booths continue.
By the way. Has anyone noticed how Ted Nugent albums just don't sound all that great anymore. The music still rocks, but there had to have been some of the most cheesy sounds on those disks I have ever heard.
Oh Slackman, I forgot to say that by adding my extention to your formula, Boston would have scored a 7.5 So really, your formula really is quite close in accuracy, with the added X BD that was omitted in it's original, flawed version. I would have given that disk a 9, unscientifically, but if science says Boston 1 is a 7.5, well, I can live with it.
Also, with that extention, if you are dealing with females in the band, instead of multiplying, you have to devide, with the exception of Ann and Nancy Wilson of Heart. There, you can still use the X in the equation. This is only fair because Nancy plays guitar better than most guys do, and Ann has balls, so she may even have a dong.
There is a male exception to the X rule though, and that is Steve Perry. It is rumored that he is female, so you must devide the problem when he is involved.

Even if the rumor proves to be false (could be tough to prove as no females are coming forward with testimony, probably a Payola deal here)the simple fact that he sounds so girly holds him to the devide rule. So that actually puts him at a O. Just about right I think.
Maybe we do have too much time on our hands here.......LOL
