Simples, substitua pela variбvel mp3player.
Se nгo tiver, crie uma

pawn Код:

new bool:mp3player[MAX_PLAYERS];

Logo sete-a no comando de comprar MP3 com o valor de true

pawn Код:

if(strcmp(cmd, "/mp3", true) == 0)
{
     if(GetPlayerMoney(playerid) < 100) return SendClientMessage(playerid, -1, "Vocк nгo tem 100 reais para comprar!");
     if(mp3player[playerid] == true) return SendClientMessage(playerid, "Vocк jб tem um MP3 Player!");
     SendClientMessage(playerid, "Vocк adquiriu um MP3 Player!");
     mp3player[playerid] = true;
}

Agora sу checar se a variбvel esta com o valor de true

pawn Код:

if(strcmp(cmd, "/music", true) == 0)
    {
        if(IsPlayerConnected(playerid))
        {
            if(mp3player[playerid] == true)//here

                    SendClientMessage(playerid, COLOR_WHITE, "|__________________ Music __________________|");
                    SendClientMessage(playerid, COLOR_WHITE, "USAGE: /music [name]");
                    SendClientMessage(playerid, COLOR_GREY, "Available names: On, Off, Next");
                    SendClientMessage(playerid, COLOR_WHITE, "|___________________________________________|");
                    return 1;
                }
                if(strcmp(x_nr,"on",true) == 0)
                {
                    GameTextForPlayer(playerid, "~n~~n~~n~~n~~n~~n~~n~~g~CD Player On", 5000, 5);
                    new channel = Music[playerid];
                    PlayerPlaySound(playerid, Songs[channel][0], 0.0, 0.0, 0.0);
                }
                else if(strcmp(x_nr,"off",true) == 0)
                {
                    GameTextForPlayer(playerid, "~n~~n~~n~~n~~n~~n~~n~~r~CD Player Off", 5000, 5);
                    PlayerFixRadio(playerid);
                }
                else if(strcmp(x_nr,"next",true) == 0)
                {
                    if(Music[playerid] == 0) { Music[playerid] = 1; }
                    else if(Music[playerid] == 1) { Music[playerid] = 2; }
                    else if(Music[playerid] == 2) { Music[playerid] = 3; }

                }
                else
                {
                    SendClientMessage(playerid, COLOR_GREY, "   Unknown music command !");
                    return 1;
                }
            }
