30 Days of Music - Day 10

Ok - todays prompt for the 30 Days of Music challenge is kind of hard.
Day 10 - For you, what song defines the 70's ?
Well, for someone who wasnt born until 1984 its kind of difficult to judge what defines an era i didnt live through. I really only have my parents album collection and the soundtrack of movies set in that decade to go off ( and, you know, what i know of history and what not ). So, with all that in mind, i'm going with this song...

Oh yea - " Rock and Roll All Nite " by Kiss!  There were so many genres of music prominent in the 70's so i went with Kiss because they were a little bit glam, a great big chunk of rock and had those amazing costumes that incorporated 70's fashion. I also think this song defines the decade where the focus moved away ( a little ) from the protesting of the late 60's/early 70's and onto more of a crumbling of those stifling societal expectations. You know, less of the traditions of the 50's and 60's and more of the " me, me, me! " attitude that would filter on into the 80's...
Ok, yep, kind of deep for a music post, but there you go. Thats my song. Play the video, turn your speakers up all the way, and rock on people!
