These files have an unknown license, were obtained from unkown sources or were compiled from third party material.
Extra considerations:
The following license file can be found in C:\Windows\System32\Drivers. Its validity is unknown due to its long-expired copyright. But honestly, so many songs already use the default MIDI anyways just from using MIDI OUT, I highly doubt anyone will chase you down over it.
