Hello there o/ So there is a Mod called "RosesAndWine" which allow you to change the music by any music that you want basically, and this mod altered also the game by not waiting julia for finishing her piano music at the proper time (save like 5-6 seconds i would say) which is not legit for top 10 times, under the top 10 times you can use any music file you want. (original MIDI, Psx music files [Legit for top 10 times], or the RosesAndWine Mod. this only occurs for Any% PC category. For 100% or any other "special" category, any music files are allowed ^^ I hope that was clear enough for you :) Have fun with this great game and good luck for future runs ;)
