Trato means “deal” or “agreement,” as in hacer un trato (“to make a deal”). In the song, “ese era el trato” refers to their agreement to stay away and have no contact, but the emotional irony is that neither person can truly keep it.
In “¿Trato Hecho?”, Colombian artist Ela Taubert sings about two exes who agreed to stay apart, stop talking, and use “contacto cero” [no contact]. The title means “Deal?” or “Agreed?”, which sounds almost playful, but the agreement is clearly falling apart. She admits, “Me miento si digo que olvido fácil” [I’m lying to myself if I say I forget easily], then adds, “Te pienso, yo te pienso” [I think about you, I think about you]. The song’s funny little twist is that they promise not to speak, then see each other “hace un rato” [a little while ago]. They call it nothing serious, but Ela knows they are both pretending, enjoying the lie for a moment.
By the end, the pretending becomes confession. “No debí soltarte, fue mi culpa” [I shouldn’t have let you go, it was my fault], she says, explaining that she was afraid of falling in love and ended up badly hurt. She still thinks about this person, misses them, and says she would not hesitate to try again if they wanted to return. The Spanish phrase “se me hizo mierda” is blunt slang for feeling completely wrecked, so the lyric is much stronger than a simple “my heart was hurt.” This is a song about a breakup agreement that looks neat on paper, while one person is still hoping to break it.
