Spotify Unveils Patent for Personalized Song Mashup Technology

Stockholm, Sweden — Spotify has filed a patent for technology that can generate personalized song mashups by analyzing and combining different tracks. The patent filing, revealed by Music Business Worldwide, outlines a system that separates songs into their vocal and instrumental components, allowing users to create custom mashups tailored to their tastes.

The technology works by first dissecting a song into its parts, then adding the vocals from one track to a selected segment of another. This innovative process allows Spotify’s algorithm to automatically layer different songs, while still giving users control over the creative choices. According to Spotify, the goal is to provide a unique listening experience that aligns with individual preferences.

The patent also discusses how the technology assesses compatibility by evaluating musical characteristics such as tempo and key alignment. It emphasizes that successful mashups require careful musical alignment to ensure smooth transitions. The filing states, “Creating successful combinations requires careful musical alignment,” which highlights the sophistication of the technology.

Spotify’s spokesperson confirmed that while this patent shares some similarities with AI music products announced recently, it remains a distinct innovation. They noted that the patent is unrelated to last week’s announcement regarding artist-first AI music products.

This patent is an extension of earlier filings, with the initial application submitted in December 2019 and granted in October 2022. Additionally, Spotify applied for similar patent protections in Europe, which was granted by the European Patent Office in June 2025.

The user experience is central to this innovation. The patent describes an interface that allows users to select a “query track” to kick off the mashup creation. The system recommends compatible tracks, giving users the power to control various aspects of the mashup. For instance, users can manipulate a slider to adjust the balance between vocal and instrumental components, making the technology interactive rather than fully automated.

Spotify has been known for its efforts to revolutionize music consumption. As it ventures further into personalized music experiences, this patented technology strengthens the company’s commitment to collaborating with artists through fair agreements. A Spotify representative stated, “We respect copyright and future innovations will be enabled with upfront agreements with artists and record labels.”

As Spotify continues to innovate, this song mashup technology could redefine how users engage with their favorite tracks, potentially transforming the music landscape as we know it.
