Babucha' is a colloquial and shortened form of "babuchas," which means "slippers" or "house shoes." It's an interesting word because it's not commonly found in song lyrics, making it unique to this track.
In the song, it's used in a very intimate and domestic context: "Y me dejas las babucha' debajo del hocico." This line paints a vivid picture of comfort and familiarity, where someone is so at home that their slippers are left right by their face, ready for them. It evokes a strong sense of belonging and the simple joys of returning home.
"Back In The City" is about the joy of coming home after being away. Alejandro Sanz and Nicky Jam sing about a homecoming: the table already set, a blanket pulled over you, slippers waiting by the bed. It's the small, familiar comforts that make a house feel like home.
The song also captures what it's like to live a touring life. The singer travels the world performing, but nothing compares to walking through his own front door, seeing his people, and eating his mother's cooking again. The city he grew up in, and the friends and family still there, are what he misses most while away.
By the end, the song turns into reassurance for the people waiting back home: even if he has to leave again, he'll always come back. The land and the people who raised him will always pull him back.
