Tiebreaker: Purple Haze Vs. Smoke On The Water?

Yesterday I took a survey on peoples' top ten favorite clic rock songs of all time. I tallied up the results in order to post them on another question like I promised, but Purple Haze and Smoke On The Water are tied. This is the tie breaking question. The results of yesterday's survey combined with today's tiebreaker will be posted to another question shortly.
