Make sure within your data folder, you have a Music folder and then the OoT music soundtrack in there. Also make sure the files are in .wav format, not sure if other music formats are supported. Under Audio, you need to go to MusicType. Add a new MusicType, MUSOcarinaOfTime, or something like that. Next go to MusicTrack and add a new track for each .wav MUSOcarinaOfTimeTrack01 or something similar to that, changing the number for each new track. Select Single Track for each of these tracks, and choose the file to be the OoT music file. Once all of the tracks are added, go back to the MusicType you created, and add each of the tracks in the order you want them to appear. Check the flag cycle tracks if you want them to go through a cycle for as long as you are in the home. Once this is done, go to Breezehome in the editor, and edit cell. Under Music Type select your new MusicType. Once this is done save and it should work when you load into game next.
