Café Tacvba's "1-2-3" feels like a sweet, slightly anxious plea to a new love to stick around. The singer is totally smitten, telling this person, "Jei Beibi, Te quiero así" [Hey Baby, I love you like this] and begging them not to disappear or lose their head. He's worried this connection might just be another fleeting story, asking, "Cómo te pido que no seas una más / De las historias que se cuentan a diario" [How do I ask you not to be just another / Of the stories told daily].
It's a song about wanting to make a good thing last, even while acknowledging the overwhelming number of other possibilities out there. The counting in the chorus, "Un, dos tres, cuéntalos bien" [One, two three, count them well], seems to refer to all the other people or experiences, but the singer just wants to keep dancing and enjoying the moment, saying, "De este baile hay que gozar" [We have to enjoy this dance]. He's ready to go wherever this person goes, declaring, "Yo voy contigo pase lo que pase" [I'll go with you no matter what happens], believing that "El amor siempre ganará" [Love will always win].
