Ожидаемым результатом было открытие и отображение деталей созданного мной альбома .............................................................................................................................................................................................................................................................................................................................................................................................................................................

Проблема здесь:

def get_absolute_url(self):
    return reverse('music:detail',kwargs = {'pk' : self.pk})
                                            ^^^^^^^^^^^^^^^^

В урлах вы передаете album_id, тогда как здесь вы передаете pk. Следовательно, изменение на àlbum_id должно исправить ситуацию:

def get_absolute_url(self):
    return reverse('music:detail',kwargs = {'album_id' : self.pk})
