Stairway To Heaven
Back in Black
Paranoid
Whole Lotta Love
Won't Get Fooled Again
Smoke on the Water
Enter Sandman
Welcome to the Jungle
Purple Haze
Crazy Train

"I'm not superstitious. I'm just a little stitious."

*Insert elitist post that over-analyzes music for the OP's top 10 lameass classic rock radio hits and mention how he is a newbie to music and a failure in life and then proceed with an all knowing statement about something nebulous like influence or comment on the musicianship of any of the songs with more authority than the ghosts of all music legends combined.*
