Movida is an interesting word that refers to a lively atmosphere, often associated with nightlife, social activity, and a general 'buzz'. It's more specific than just 'movement' and evokes a sense of excitement and energy.
In the song, ANNA sings, "Tu puoi trovarmi dove c'è movida" (You can find me where there's movida). This suggests she's always at the center of the action, where things are happening and the energy is high, making it a cool and enticing word to learn.
ANNA spends most of this song counting what she has, then spends the last minute admitting what it did not buy. The verses are pure flex: "Bevo vodka dalla Stanley" ("I drink vodka out of the Stanley"), and a night out where "Mi amano tutte, bionde, rosse, more" ("They all love me, blondes, redheads, brunettes"). She is funny about where she came from, too. "È normale che sono a disagio se vesto elegante" ("It's normal that I feel awkward if I dress up smart") is a girl from nothing describing what money still feels like on her.
Then the bridge drops the act. "Tutti questi cash non aggiustano il cuore a metà" ("All this cash doesn't mend a heart in half") and "Volevo essere donna prima di Dolla $ign" ("I wanted to be a woman before a dollar sign") are the lines the title hangs on: the million dollar babe is the packaging, and the chorus already told us the rest, "Ho il mio cuore seppellito" ("I've got my heart buried"), "Sotto a tutte queste chain" ("Under all these chains"). She still gives the last word to a joke, though. "L'ha detto anche Mattarella" ("Even Mattarella said so") calls in the President of Italy as her character witness.
