Curiously, since you're a Kiss fan, what is your opinion on their 1979 disco-metal hit " I was made for Loving You" that at the time sort of hurt their credibility amongst their old hardcore fan base and alienated fans of other metal bands like Black Sabbath and Led Zeppelin?
Me personally I think it took some guts to branch out and explore some new musical territory and I think, even by 1979, the band realized their great 1970's "forever party" would be coming to an end and the 1980's, unquestionably with punk, pop metal and new wave leading the way, would be a very different decade in terms of musical varieties and tastes.
