Unfortunately, the term "Legado" can refer to various artists and groups across different music genres, and without specific details on the genre or background of the artist in question, it's challenging to provide an accurate biography. However, if no well-known artist or group is associated with the releases mentioned, it's possible you are referring to an emerging artist or band. In that case, I'd craft a more generic biography, which can be tailored once more specifics are known:

Legado is a rising musical act that has been capturing the hearts of listeners with their soulful and passionate tracks. Their music is known for its emotive lyrics and powerful delivery, which resonate with fans across borders. With recent releases including "Alzo Mi Voz," "¡Ayúdame!," "No Te Importó Lo Que Fui," and "Todo por Mi," Legado has started to carve out a niche for themselves in the music industry. Each song showcases the artist's or the group's depth and versatility, addressing themes of empowerment, pleas for assistance, reflections on past relationships, and personal growth.

Despite being relatively new to the scene, Legado has demonstrated a maturity in songwriting and an ability to connect with listeners on an emotional level. With each release, they have broadened their reach and are quickly becoming known for their unique sound. While details about their background are still emerging, the music of Legado speaks for itself—earnest, impactful, and reflective of the diverse human experience. Fans are eagerly awaiting more material as Legado continues to build upon their discography and make their mark in the music world.
