"Main Theme - Metal Gear Solid" is a low quality rip of "Main Theme" from Metal Gear Solid.
Starting at 0:05, the advertised track becomes an off-key mashup with "All Star".
This rip was uploaded to the SiIvaGunner channel on May 18, 2016. Because of its poor quality, the rip was unlisted and removed from the Metal Gear Solid playlist. It was later replaced by "Main Theme (super remastered not gay version) - Metal Gear Solid". It was also mocked in the Mr Rental rip, "Options - Mr Rental: The Video Game".
