The Rockman 11 Official Soundtrack's second disc is home to several all-new arranged pieces, apparently. These are completely different from the DLC "Wily Numbers" tracks, and you can listen to a few samples in the video above (jump to 1:34).
Stylistically-speaking, each track is pretty different from one another. They're VERY different from the game's default soundtrack. I'm looking forward to hearing the rest!
The Rockman 11 official soundtrack goes on sale in Japan November 14th. Snag a pre-order from Play-Asia.
