Cora' is a popular slang abbreviation of the word corazón, which translates to 'heart'. Dropping the final syllables of words is a very common stylistic choice in Caribbean Spanish and urban music.
In the song, Feid sings, "Si le duele el cora', que se tome un Panadol" (If her heart hurts, she should take a Panadol). It is a highly memorable and witty line where he playfully suggests fixing emotional heartbreak with basic over-the-counter pain medicine!
Colombian hitmaker Feid gives us the ultimate post-breakup reality check in "Normal". The situation is messy: he was giving 100% while she only gave half, sleeping beside him while seeing someone else ("Yo durmiendo contigo y tú con otro te acuestas" [I was sleeping with you and you sleep with someone else]). Now that they are over, she is hitting the club every weekend hoping to run into him, calling him drunk, and pretending to cry over him in another person's bed. Feid's reaction? Shrugging it off with a sarcastic "Normal" ("Normal, si te sientes solita y me extrañas" [It's normal if you feel lonely and miss me]). Nobody is buying her sob story when she brought it on herself.
Feid balances genuine hurt with hilarious levels of petty confidence. He admits that forgiving her is too hard, but he is definitely not sitting around moping. Instead, he is in Los Cabos making money ("están lloviendo los chavos" [money is raining down]), dancing with someone new, and offering some cheeky medical advice: if her heart hurts, she should take a Panadol painkiller ("Si le duele el cora', que se tome un Panadol" [If her heart hurts, let her take a Panadol]). He points out Colombian and Caribbean slang along the way, calling reckless guys "gatos malos" (bad cats / bad boys) and calling out her fake social media smile ("Bebé, si en la foto te ves feliz" [Baby, you look happy in your photo]). It is a bouncy, direct track about moving on, getting your lick back, and watching your ex realize what they lost.
