How to create a linked dynamic list inside another dynamic list in C?

I'm having a hard time getting a dynamically linked list inside another using data structure. I can create a dynamic list, but I can not create another one within it.

To illustrate what I mean:

I have a list of Bands ; each band is a list of albums ; and each album is a list of music . And in the program the user can include songs and remove them whenever they want, include albums and remove them whenever they want, and include bands and remove them whenever they want.

My code is like this, but it does not work, must have a lot of nonsense :

.C file

#include "biblioteca.h"

ElemM *lm;
ElemA *la;
ElemB *lb;
//---------------------------MAIN--------------------------------->

int main()
{
  lb = cria_lista_banda();
  la =  cria_lista_album();
  lm = cria_lista_musica();


  system("PAUSE");  
  return 0;
} 
//----------------------------------------------------------------->

ElemB *cria_lista_banda(){
        ElemB *lb;
        lb =  malloc(sizeof(ElemB));
        lb->prox_banda = NULL;
        return lb;


}

ElemA *cria_lista_album(){
        ElemA *la;
        la =  malloc(sizeof(ElemA));
        la->prox_album= NULL;
        return la;


}

ElemM *cria_lista_musica(){
        ElemM *lm;
        lm =  malloc(sizeof(ElemM));
        lm->prox_musica= NULL;
        return lm;


}

int incluir_musica(ElemM *lm, ElemA *la, ElemB *lb, int id_m, int tempo, char *nome_m, int id_a, int id_b){
        int valor1, valor2, valor3, i;

        valor1 = busca_banda(id_b, lb);
        valor2 = busca_album(id_b, id_a, lb, la);
        valor3 = busca_musica(id_b, id_a, id_m, lb, la, lm);
        if(valor3 == -1) return -1;

        ElemB *q;
        q = lb->prox_banda;
        for(i = 0; i <= valor1; i++){
              q = q->prox_banda;
        }
        ElemA *p;
        p = q->albuns_da_banda->prox_album;
        for(i = 0; i <= valor2; i++){
             p = p->prox_album;         
        }

        ElemM *novo, *novocpy;
        p->musicas_do_album->novo = malloc( sizeof(ElemM));
        novocpy = p->musica_do_album->novo;
        if(novo == NULL) return 0;
        novocpy->id_musica = id_m;
        novocpy->tempo_da_musica = tempo;
        strcpy(novocpy->nome_musica, nome_m);
        novocpy->prox_musica = lc->prox_musica;
        lm->prox_musica = novocpy;
        return 1;
}

int busca_banda(int id, ElemB *lb){
        int cont = 0;

@ pedro-witzel and @hugomg, the above files have been edited for how they are now. They are not working and the fonts I am using to try to solve this problem do not talk about list inside another, and I can not find anything related to it, just how to make a "normal" linked list, could they help me one more time? / p>

Note: The value -1 indicates that something happened and made the program not reach the goal.
