ONErpm Launches “The Lost Files” to Revive Artist Archives and Expand Catalog Reach

From YouTube leaks to official playlists—ONErpm transforms lost tracks into high-performing catalog assets.

ONErpm has launched The Lost Files, a catalog initiative focused on curating and activating early artist material that was never formally released.

Designed to reclaim leaked or fan-shared content scattered across YouTube and social media, the project turns long-missing songs into structured, music-streaming-ready-albums. The strategy strengthens catalog value while delivering long-awaited content to loyal fanbases.

Cosculluela's The Lost Files includes 22 foundational songs

The first two volumes feature artists with deep roots in Latin urban music: Cosculluela and El Micha. Each release compiles early tracks that shaped their underground followings. Cosculluela's The Lost Files includes 22 foundational songs like “Deja un Mensaje,” “Este Es Mi Momento,” and “Mandela”—rare cuts that helped define his voice.

El Micha's volume brings together key early tracks such as “Si, Como No,” “El Dulcero,” “Alibaba,” “Jevas, Fumadera y Tomadera,” and “No Perdona,” finally giving fans access to music that had existed only on unofficial channels.

Micha's The Lost Files gave fans access to exclusive music.

ONErpm handled the full pipeline—from discovery to delivery. Teams audited the artists' unofficial content, verified rights, curated tracklists, and distributed each volume through official artist profiles.

The campaign activated DSP pitching, editorial playlisting, internal newsletters, and press coverage to frame The Lost Files as a broader catalog strategy.

On YouTube, tracks were re-uploaded with official cover videos, and previous duplicate uploads were taken down to drive traffic to the correct sources.

Compilations delivered strong and immediate growth: 

Following the release of El Princi: The Lost Files, ONErpm recorded strong platform-specific growth driven by a smart catalog strategy and high fan anticipation. No paid promotion supported the launch—results were fully organic.

On Spotify, daily streams increased by nearly 13% on release day. Save rates and playlist additions outperformed typical catalog benchmarks, signaling strong listener engagement. Although the album received no initial editorial placements, fan traction helped build momentum week over week.

YouTube saw an immediate traffic surge, with Cosculluela's channel growing by 156% overnight. The upload of 22 official audio covers helped replace unofficial versions while consolidating fan activity. Subscriber count jumped by 10% in just one week, a notable gain for a catalog-focused release.

From an audience engagement standpoint, fans welcomed the project as a long-awaited gift. Many praised the official availability of previously leaked tracks, and their excitement helped fuel discovery. Although Cosculluela had not planned to promote the release, the strong fan response led him to share the project across TikTok, Instagram, and Twitter days later.

The success of The Lost Files shows the power of catalog optimization. With the right timing, cleanup, and platform support, unoficially unreleased material can become a valuable growth asset—deepening fan loyalty and driving measurable impact across streaming services.

The Lost Files is now a key part of ONErpm's catalog development strategy—offering a repeatable model that reactivates legacy material, deepens artist narratives, and transforms fragmented history into long-term value.
