Jodío is a colloquial and somewhat vulgar past participle of the verb joder, which can mean to 'screw up', 'mess up', or 'be in a bad situation'. It's a very common slang term in many Spanish-speaking countries.
In this song, Hades66 uses it to express the hardships and struggles he has endured, as in "Ninguno sabe de to lo que yo me he jodío" (No one knows all the ways I've been screwed over/messed up). It conveys a raw and authentic feeling of having faced significant difficulties in life.
Hades66 kicks off this track with a prayer, setting a really personal and reflective tone. He's talking directly to God, saying "Padre nuestro que estás en el cielo, Santificado sea tu nombre" [Our Father who art in heaven, Hallowed be thy name]. It's clear he's been through a lot, because he immediately gets into how no one really knows his struggles. He says, "Ninguno sabe de to lo que yo me he jodío, Ninguno sabe, cabrón, to lo que he perdío" [No one knows all that I've been through, No one knows, damn, all that I've lost]. He admits that fame and money had him confused, and that nothing could fill the emptiness he felt.
But this isn't a sad song for long! Hades66 quickly turns it around, saying he's blessed by God and has achieved everything. He's a survivor, declaring "Si me caigo, me levanto, Ya lo he hecho de todos modos" [If I fall, I get up, I've done it anyway]. He talks about how much he's grown, moving past his old life and embracing his new role as a singer. He even sends blessings to everyone, including his enemies, showing a lot of maturity and gratitude. It's a powerful intro about overcoming hardship and staying true to himself, with a lot of thanks to God for everything he has now.
