"Solid State Scouter - SiIvaGunner: King for Another Day" is a high quality rip of "Solid State Scouter" from SilvaGunner: King for Another Day. It represents the King for Another Day Tournament contender Dr. Piccolo.
This is a remix of "Solid State Scouter" from Dragon Ball Z: Bardock - The Father of Goku. The remix begins with a sample of the opening to "Technopolis" by Yellow Magic Orchestra, referencing "Solid State Scouter"'s similar opening (which was likely intentional, since "Technopolis" was on the album Solid State Survivor). In addition, clips of Bardock's dialogue are heard throughout the remix.
