I searched everywhere to find this piece. I even tried the android app called Shazam.
It wasn't long enough to be recognized by Shazam. I'm talking about episode 296.
The track starts at 21:48 (when Franky shows up). Here's a link to the episode.
It's the scene where Franky shoots Chopper.
Could you guys please help me out? This piece really inspires me.
