Contagié is the past tense of the verb contagiar, which means "to infect" or "to spread". While this word can have a negative feel, J Balvin uses it here in a clever and positive way.
He sings, "Dime si te contagié" (Tell me if I infected you), asking if he has successfully passed on his good energy and positive vibe. It's a great metaphorical use of the word that captures the song's theme of spreading happiness as if it were contagious.
This song is a shot of pure energy from Colombian superstar J Balvin! It's all about having a winning attitude and spreading good vibes. He kicks things off by talking about his team, saying, "Mi equipo está puesto en la raya / Sé que no me fallan" (My team is on the line / I know they won't fail me). It's a song for anyone who feels like they're on the verge of a big win, ready to go for the "medallas" (medals).
The whole point is to stay positive, even when it's hard. J Balvin says it directly: "Positivo, por más difícil que se vea, siempre positivo" (Positive, no matter how difficult it looks, always positive). He wants to share this feeling, asking, "Dime si te contagié" (Tell me if I infected you) with his good mood. It's a call to celebrate life right now, because as he puts it, "la vida es una y tenemos que gozar" (there's only one life and we have to enjoy it).
