Play an mp3 with SDL2

gistfile1.c

#include "SDL2/SDL.h"
#include "SDL2/SDL_mixer.h"

static const char *MY_COOL_MP3 = "cool_tunes.mp3";

int main(int argc, char **argv) {
    int result = 0;
    int flags = MIX_INIT_MP3;

    if (SDL_Init(SDL_INIT_AUDIO) < 0) {
        printf("Failed to init SDL\n");
        exit(1);
    }

    if (flags != (result = Mix_Init(flags))) {
        printf("Could not initialize mixer (result: %d).\n", result);
        printf("Mix_Init: %s\n", Mix_GetError());
        exit(1);
    }

    Mix_OpenAudio(22050, AUDIO_S16SYS, 2, 640);
    Mix_Music *music = Mix_LoadMUS(MY_COOL_MP3);
    Mix_PlayMusic(music, 1);

    while (!SDL_QuitRequested()) {
        SDL_Delay(250);
    }

    Mix_FreeMusic(music);
    SDL_Quit();
    return 0;
}

That's don't work here, don't know why. But I can compile it.
