Is 'la' here a direct object? I think that it is, but I am not sure.
Only Lui and leur are indirect objects, no?
Cette chanson la rend complètement folle
Is it " cette musique la rend absolument folle" wrong?
how do we know whether to use "la" or "lui"?
I guess it's trickier than most, but it can only be a Direct Object. It is making her crazy, not to, for or from her.
