OoT3D All 12 Songs in inventory

This is a written explanation of the puzzle goal I made in November 2018, "All 12 Songs in inventory" .

The goal of the puzzle is to obtain all 12 ocarina songs' scores in your inventory as described in title.
You must have all scores in inventory at the end of the game, so only the fact you have learned each songs once is not enough to win. If you lose one song for some reasons, you should get it again for the win.

Here are the rules :
If i say "dungeons" here, this includes not only main 8 dungeons and 3 mini-dungeons but also the last dungeon.

-You can open a chest only once for Kokiri Sword chest in Kokiri Forest. Opening other chests, regardless of its size or appearance, is no-no.
-You can't enter dungeons with Wrong Warp, either directly or in WW chain.
-You can't enter dungeons as child.
-You can't kill any enemies outside the dungeons for following purposes.
--For triggering some stuffs, buying some from scrubs, getting their drops.
---Killing them by accident is an exception.
----e.g. You must not kill a stalchild with bomb, but it is ok if you kill him accidentally with bomb blast that is for appearing a grotto.
-Update the maximum number of possession is banned even if it doesn't have receptacle. So you can't upgrade sticks, nuts, bomb bag, bullet bag, quiver and wallet.
-GIM, NG+, Back in Time are banned ofc.
-Scarecrow's Song doesn't count

This puzzle includes many new tricks in this year.
I wonder if it is trouble to complete, but I hope it's at least fun to think about.
