Five best rock songs of all time

This came up in conversation recently. I had been on the treadmill and one of my top 5 came on and I was thinking about how different it is to rock out on the treadmill to a song like that versus the others on the play list. Later that week at a bar, I talked about it with some friends while a very mediocre Lynyrd Skynyrd band played (I would like those few hours back, please). So let me frame the question.

What are your 5 top rock songs of all time? Yours, not everyone else's. I'm not necessarily looking for the best technically. Just your favorites; the ones that make you rock out. Where you are all air guitaring and stuff. And I am limiting the question to the rock genre. I buzzer will sound of your song isn't rock.
