Final means 'end' or 'finish'. While it's a common word, its significance in this song is quite special.
In this track, ROSALÍA is directly addressing her listeners, thanking them for staying with her through the entire album. She says, "Parece ser que hasta el final" (It seems that until the end), acknowledging their dedication. This makes 'final' a powerful word in this context, symbolizing the completion of a journey and the bond between artist and fan.
Think of "Thank Yu :)" as a direct voice memo left at the very end of ROSALÍA's album. There is no heavy beat or complex production here. Instead, she starts by sorting out her sound check in English: "Not really, not really / I don't hear my voice so much", switching quickly between languages until everything sounds right with "Ahora sí, now amazing, amazing" (Now yes, now amazing, amazing). Her bilingual back-and-forth gives you a peek behind the studio glass, complete with warm chuckles and everyday hesitations like "Amm, también, bueno, mmm" (Umm, also, well, mmm).
Then she drops right into her signature intro, "Hola, soy la rosalía" (Hello, I am Rosalía), speaking straight to you. In Spanish, putting the definite article la before a woman's name is a casual, affectionate habit in certain regions, and she owns it completely as her calling card. She points out that you stayed for the ride: "Y has escuchado motomami / Parece ser que hasta el final" (And you have listened to Motomami / It seems to be until the very end). It is a warm, unscripted thank-you note that wraps up with an accidental slip and a laugh: "Ups, jajaja" (Oops, hahaha). Sweet, short, and very human.
