"Copenhague" is Morad stuck on someone he knows is bad for him. He opens with "Es que no es normal, ya no te tengo" (It's not normal, I don't have you anymore), and then hears she was seen walking around her neighbourhood with another guy. He admits he can't read her: "No entiendo tu juego" (I don't get your game), and she has him "en mareo", literally seasick, which is Spanish slang for dizzy and confused.
The hook is where the bitterness comes out. He talks about her in the third person: "No coge el teléfono" (She doesn't pick up the phone) and "Si me habla, le diré que no" (If she talks to me, I'll tell her no). It sounds tough, but a few lines earlier he admits "siendo tú la mala... de noche yo te veo" (you being the bad one, I still see you at night). The second verse throws shade at the new guy: "a él le falta ritmo" (he's got no rhythm). Petty, and pretty funny.
Learner tip: watch the -ndo forms stacked up: queriéndolo, amándolo, perdiéndolo (loving it, wanting it, wasting it). The pronoun sticks to the end of the gerund, so you get a written accent to keep the stress in place.
