Second Round Results - One Band, One Song

It's been so fun to see how this tournament is playing out so far.  I hope everyone keeps voting until there's only one song left.
Here are the results for the second round:
One Band, One Song Rock Tournament
This round had several upsets (according to the seeding), which included Elton John and Jimi Hendrix being left behind.  On a side note, does anyone know if there's an easier platform to do this type of tournament bracket?
I know it would be so much easier for people to participate if they only had to click and vote for the songs they wanted to advance.  Does anyone have any suggestions on how to accomplish this?
I'll continue to tally the votes that you send to me and I'll post the results for the third round next Sunday.
