This is a hard poll. I was very much anti-'70s for a LONG time growing up. Part of that was I just didn't like the overall '70s rock sound and production very much. Part of it was just misplaced rebellion on my part of getting into '80s hard rock as my first real passion in music. So songs from the late '60s and '70s, as well as bands from that era that were releasing songs into the '80s that still had that '70s sound, were something I avoided like the plague. I have since come to appreciate a lot of stuff from that era, although I still have a bias against some of it (more for the sound/production issue than anything else).
I went with the following:
-Smoke on the Water: I am hot and cold on Purple, just depending on the song. This one is such a blast to play live with a band that it holds a special place for me.
-Iron Man: (somehow, I missed and clicked the Stones instead--oops) This was one of the first hard rock songs I knew and loved. It is also the first song I learned to play on guitar. I can't say I was ever really a Sabbath "fan," but their "hits" from the Ozzy era are some of the first hard rock I was exposed to.
-Comfortably Numb: Probably my favorite song on the list.
-Tom Sawyer: Not a Rush fan by any stretch. Not even a little. But this is one of a handful of songs from them that I really like.
-Bohemian Rhapsody: The "Wayne's World section" alone earns this song a spot. This is another band that I am hot and cold on. I really like some songs. But I cannot consider myself a fan of the band as a whole, as a lot of their stuff just doesn't connect with me. But "The Game" was the first album I ever bought in my life, so they will always be a special band for me. But good song.
Won't Get Fooled Again just missed for me. It was the next song up and would have gotten chosen if not for the others on the list. The Who are definitely one of those bands that I wrote off in my younger years that I have come to appreciate much later in life. Hate to say it, but I owe that to CSI Miami and DT covering their songs, or else I might never have given them a chance. Hey, whatever it takes, right?
