Arañazos literally translates to 'scratches' or 'claw marks'. It is a striking and highly visual word that stands out because it is rarely used in typical pop songs.
In these lyrics, Jeanette uses it metaphorically when she sings about "arañazos en el corazón" (scratches on the heart). This creates a vivid, passionate image of emotional pain that perfectly matches her comparing herself to a wounded panther (pantera herida) earlier in the song.
Jeanette brings pure dramatic commitment to "Ojos En El Sol", turning a breakup into a full-blown mythical quest. Right from the start, she wanders alone with scratches on her heart ("arañazos en el corazón"), but she refuses to give up. Instead of sulking quietly, she calls herself a wounded panther ("pantera herida, no me rendiré" / 'wounded panther, I will not give up'). It is over the top, vivid, and fantastic.
Her dedication goes to extreme lengths: she promises to stare straight into the blazing sun just to search for you ("Pondré mis ojos en el sol, buscándote" / 'I will put my eyes on the sun, looking for you'). The Spanish expression "sol a sol" (literally 'sun to sun') means working tirelessly from sunrise to sunset, and she uses that tireless energy to keep chasing a lost love. Between hearing calling voices in the ocean waves ("voces en el mar") and treating the rain as weeping sky tears ("lágrimas del cielo"), she makes the entire natural world take part in her search until you finally return.
