Eric Singer has a message for Kiss fans still angry over other musicians wearing the founding members' makeup: time to move on.

"Now, maybe I'm looking at it too black and white, but for me, I just don't really fully understand fans, or former fans, that have that point of view," Singer, who has appeared with Kiss off and on since 1991, told Cassius Morris. "I get the passion part, I get that a band like Kiss means a lot to them, or it had a real impact on their life. I get it. But it had a real impact on me too -- 'cause guess what? I play in the band, you know, so of course I care. It means something to me. But I don't understand the people that can't just move on. If you don't like it, or you have a problem with something, respectfully just move on ... For those who like it or wanna enjoy it, cool."

Singer first played with Gene Simmons, Paul Stanley and Bruce Kulick from 1991-96, and then with Simmons, Stanley and Ace Frehley from 2001-02. The current lineup featuring Tommy Thayer in Frehley's place debuted in 2002. A decade later, Singer thinks fans have had plenty of time to come to terms with the four members who play in Kiss today.

"I'm not saying that you should just blindly go, 'Oh, I agree with anything the band does and I don't care,'" Singer said. "What I'm saying is, if you really, really have a distaste for it, if you're gonna be mad just because the band is not doing what you want, then go, 'OK, I'm not into it anymore.' That's what I did my whole life when it came to bands. When a band kind of changed the musical sound or direction and I kind of lost interest in them, I stopped buying the records and I didn't go to the concerts. ... I just said, 'OK, well, I'm not really into it anymore.'"
