Greg Merman is...

Little Mac (the Challenger)
His opponent:
Billy is...

Piston Honda! (the champ)
Round 1:Piston Honda/Billy:
The Flying Burrito Brothers – My Uncle
Some twangy group singing. Not really my cup of tea, but it's inoffensive. 5/10
Greg/Little Mac:
Teenage Head – You're Tearin' Me Apart
This is the proper way to ape the Ramones. And I believe this is the 2nd Canadian band you've pulled thus far. 8/10
Little Mac comes out swinging, taking it to the champ with a 3 point lead. If he can score another 8/10+ in either of the next two rounds, he'll score himself a TKO!Round 2: Piston Honda/Billy:
The Broadways – Everything I Ever Wanted To Know About Genocide I Learned In The Third Grade
Ha, I remember this song. I would've ranked this a lot higher 10 years ago, but not feeling it as much today. 5/10
Greg/Little Mac:
The Leftovers – Run Away
Love these dudes. One of my favorite young bands doing it today. 7/10
Mac comes within one point of TKO'ing the champ in Round 2, but Honda stays resilient. Still, Mac is 5 points up on the scorecard, meaning Piston can only win this fight by a 10/10 KO or by taking the next round by 8 or more points!Round 3:Piston Honda/Billy:
Chinese Telephones – It's Starting Again
I really like these guys. Just straight-up rock with no pretense. 7/10
Greg/Little Mac:
The Dopamines – Structural Failure
Greg's station is rocking one after another. This is some good stuff. I think once I hear a few good punk tunes in a row, I start overrating songs, so lucky for you! 7/10
It was a back and forth battle in Round 3, giving neither fighter the edge. Fortunately for Mac, he had the champ on points coming into this round, so Mac is your new lower division champ!!Judges' scorecard:
Piston Honda - 17
Little Mac - 22
Little Mac wins!

Little Mac has earned himself a save point starting at Don Flamenco, with all 3 continues still in tact!
Good work, Greg
