“Moscow Mule” opens Bad Bunny's 2022 album Un Verano Sin Ti (a summer without you). It's named after a cocktail of vodka, ginger beer and lime, and it sets the mood for the whole record: the beach, the heat, a drink in hand, and an attraction he wants to enjoy without turning it into a serious relationship.
The beat is mellow and tropical, and his delivery is relaxed — one of his easier songs to follow, though still full of Puerto Rican slang and English loanwords.
It's a good song for the vocabulary of a summer night — the drink, the beach, to go out, to fall in love (or not) — and for hearing how Bad Bunny bends Spanish vowels and drops consonants when he sings.
