In general trying to convert audio record files into MIDI renders poor results due to the ways the formats differ from each other. You might find some tool online that promises to do it but results might not sound quite like what you want them to. A more resonable solution might be disabling the ingame music and running a media player in the background.

in that case perhaps someone has a tool like Advanced Genie Editor, RockNRor or the composite editor that can make the gameplay music play certain other files?

im not aware of any that does nor do i know how to figure that out because im an idiot
