Pokered music error

[Raichu]

Hello. I was replacing the music in my Pokered hack with other files, but when I replaced Cities1 with something else it gives me these errors.

$ make

rgblink -p 0x00 -d -m pokered.map -n pokered.sym -l layout.link -o pokered.gbc audio_red.o home_red.o main_red.o maps_red.o text_red.o wram_red.o gfx/pics_red.o gfx/sprites_red.o gfx/tilesets_red.o

I replaced it with the original Cities1 music, but it still gives this error. I also replaced audio.asm and alternate_tempo.asm with their vanilla counterparts, but it STILL gives this error.

Here is my Pokered folder~

EDIT: I was able to fix the issue by updating the music headers. I replaced the music with the vanilla one but forgot to update the music headers.
