Andadas literally means 'walks' or 'strolls', but in the phrase "volver a las andadas", it takes on the idiomatic meaning of 'returning to old habits' or 'going back to one's old ways'. It often implies a return to mischievous or undesirable behaviors.
In this song, the singer uses it to express a return to a wilder, single lifestyle after a breakup, singing "Vuelve a las andadas" (Go back to your old ways) and later, "Tocará, ni modo, volver a andar de loco" (I guess I'll have to go back to being crazy). This word is interesting because it captures a common human experience of reverting to past behaviors, especially after heartbreak.
Ever had a relationship that felt perfect one minute and was completely over the next? Armenta and Jorsshh capture that confusing and painful moment in "DE NUEVO." The song opens with the singer in shock, asking his partner what went wrong. They used to be great, but now they're fighting over silly things, and she's telling him she doesn't love him anymore.
Faced with a sudden breakup, the singer tells himself he has no choice but to go back to his old ways: a life of parties and casual flings. He sings about going back to being "loco" (crazy) and being seen out at wild parties. But even as he tries to move on, he can't stop thinking about his ex. The song ends with him sitting in a bar as it's about to close, still thinking about calling her one more time, showing that it's not so easy to just forget someone.
