Did your love for a band change when you found out some of them didn't play their part on the album, where a guest played, but not credited?

In recent years we start to hear about things like Ace Frehley didn't play lead on Kiss's Sweet Pain, or that he was on the cover of Creatures Of The Night but didn't play on it. Various sources saying Nikki Sixx didn't play bass on most of the early Motley Crue albums or when producer Jack Douglas replaced Joe Perry and Brad Hamilton with Steve Hunter and Dick Wagner on Get Your Wings? There are many more stories on this happening in the studio. Were you disappointed, didn't care. I found it interesting.
