This particular idea is to split specific tracks into respective tracks that would allow for more randomized tracks playing, for example the Shadow Temple themes plays in both Shadow Temple and Bottom of the Well splitting these up would allow for 1 track per area instead of sharing the same track on both areas, another example is Hyrule Field that plays in many areas including Lake Hylia. Death Mountain Trail, Zoras River, and Zora's Fountain iirc so there isnt to much variation throughout a run or can make it feel like you listen to 1 single track which can get annoying so i then randomize the tracks often
This could apply for boss battles as well and make every boss have its own track when randomized.
