Abasto literally means 'supply' or 'provision'. It's a fantastic word to learn because it's the key to the common Spanish idiom "no dar abasto", which means "to not be able to cope" or "to not have enough of something".
In this passionate salsa track, Marc Anthony sings, "Y no me doy abasto", expressing that his love is so immense that even giving his partner everything he has still doesn't feel like enough. It's a powerful way to describe an overwhelming, all-consuming love, and learning this idiom is a great way to sound more like a native speaker.
This song is one of the most over-the-top, passionate declarations of love you'll ever hear. Marc Anthony isn't just saying he's in love; he's asking, "¿Qué precio tiene el cielo?" [What is the price of heaven?], because he's ready to buy it for the person he loves. He feels his love is so boundless that there are "faltan frenos al quererte" [no brakes when it comes to loving you]. It's a love that feels completely natural and has totally taken over his life.
He wants to give more than just affection; he wants to "regalarte el azul de los días" [gift you the blue of the days]. He feels like he's already in heaven, or "gloria" [glory], just by being with this person. And he's willing to pay any price to keep it that way, offering up his soul and his life. It's a classic, fiery salsa track about a love that feels bigger than the entire world.
