Gran Rah's "Dejarlo Ir" is all about putting yourself first and letting go of what doesn't serve you. He tells us that we are "lo más importante, el centro del universo" [the most important thing, the center of the universe] and that love isn't something you beg for, but something you share. If someone isn't putting in the effort, then "salte" [get out]!
He's not going to waste his life on someone else's dreams if they don't support his, saying "no perderé mi vida en otra vida si no sanas mis heridas menos si no sincronizas mis sueños" [I won't lose my life in another life if you don't heal my wounds, much less if you don't synchronize my dreams]. The song is a powerful reminder to stop fearing loneliness and to embrace the idea that if someone comes along, great, but don't ever say "que no" [no] to yourself. It's time to "dejarlo ir" [let it go]!
