While not explicitly in the lyrics, "Imperdible" is the title of the song and a key concept. It means "unmissable" or "something that cannot be lost."
In the context of the song, the artist repeatedly lists things he could lose—his way, his rhythm, his mind, even his breath—but ultimately concludes that he will never lose the person he's singing to. The title encapsulates this central theme of enduring connection despite all potential losses, making it a powerful and enticing word.
Rayden's "Imperdible" (Unmissable) featuring Sidecars is a really cool song about embracing all the things you might lose in life, because some things are just too important to ever truly let go of. He talks about losing his way, like "Podré perder el norte" (I could lose my way) or getting lost "en donde tu espalda pierda su nombre" (where your back loses its name). He even mentions losing his rhythm, manners, and temper, but never "las ganas de sentirme vivo si hay motivos" (the desire to feel alive if there are reasons).
It's all about finding beauty in the chaos and the uncertainty. He'd rather "morir viéndote a no ver quien pudo hacerlo" (die seeing you than not see who could do it), showing a deep commitment. Even if they get lost just to find each other again, or if the world spins around them without a care, he knows that some connections are "imperdible" – unmissable. He says, "nunca me vas a perder" (you're never going to lose me), which is a powerful message about lasting connection and finding joy in the journey, no matter what gets lost along the way.
