I'm not the biggest Crue fan ever. In fact, I'm not even a big Crue fan at all. I think, in retrospect that their songs, even most of their best songs, were mediocre, and highly overrated. That being said...
The Crue were the biggest hair band of the 80's, period. Even if their songs don't stand the test of time, they were the most popular band in the most popular genre of music for several years. Every decade has bands that everyone remembers, from Elvis in the 50's to The Beatles in the 60's and Led Zeppelin and Kiss in the 70's. Motley Crue and Def Leppard were those bands from the 80's. Bad songs or not, the Crue will not be forgotten. Anyone who thinks they will understands little about what that band meant to music in the 80's.
If it don't shock, it don't rock, we'll be lipstick junkiez till the end of time!!!
