It seems that "500" refers to a musical artist with a palette of diverse music releases, although without widely recognized information about them, it’s challenging to offer a comprehensive bio. However, based on the titles of their recent releases, "500" appears to be an artist who traverses various themes and perhaps genre boundaries – from introspective tracks like "21 insecurities" and reflective pieces such as "48 months", to commentary on materialism with "Cash Rules." Their body of work suggests an engagement with both modern production and thematic depth.

The titles "Straight Autotune" and its deluxe version hint at a willingness to embrace contemporary sonic trends, perhaps indicative of an artist who operates within the realm of pop, hip-hop, or electronic music. The mention of a "NEW VOICE" release could imply a reinvention or evolution in their musical style or persona. The diversity in their catalog is further evidenced by "Aint my Fam," suggesting themes of relationship and loyalty, and "Free Bango," which may carry a narrative or personal significance. "Home & You" possibly explores more intimate terrains, while "march of bucentaure" intrigues with its potential historical or cultural references. Lastly, the release titled "爱情解药" indicates that "500" may also experiment with different languages and cultural elements, offering a song related to love's remedy or antidote, as the title could be translated from Mandarin. Despite the limited information provided, "500" appears to be an enigmatic and versatile figure in the music industry.
