to change the subject
Já estou cansada deste tema, vamos trocar o disco, por favor!
I'm tired of this topic, let's change the subject, please!
Trocar o disco ("to change the record") comes from the age of vinyl: once a record had played through, or you were simply tired of the same song, you swapped it for another. Asking someone to trocar o disco is asking them to drop a worn-out subject and talk about something else.
