How to modify the value of an element of an array in mongodb?

The fact is that I have the following document and I want to modify the duration of the song Sleepwalker, but before reaching it there is an array. I have tried to modify fields that although they are nested they do not contain arrays and it has worked for me, but with this code it does not let me modify it, I imagine that by the array.

My query is:

db.discos.update({"album.Pistas.titulo":"Sleepwalker"},{$set {"album.Pistas.minutos":"5:55"}})

But I get the error:

"errmsg" : "cannot use the part (Pistas of album.Pistas.minutos) to traverse the element ({Pistas: [ { numero: 1, titulo: \"Sleepwalker\", minutos: \"5:54\" }, { numero: 2, titulo: \"Washington is Next\", minutos: \"5:19\" }, { numero: 8, titulo: \"A tout le monde\", minutos: \"4:11\" } ]})"

How can I modify it?
