Karaoke Tracks vs MusicLM

x-minus.pro is a karaoke backing track library where you can search, play, and download tracks across genres and languages. The site hosts a community catalog with over 700,000 tracks, organized into collections by genre, language, and theme.

You can shift the pitch of any track to match your vocal range, build playlists, and browse recent uploads or the top 50 chart. Registered users can upload their own karaoke tracks to share with the community.

The site also includes separate online tools for vocal removal and pitch or tempo adjustment. The vocal remover uses multiple stem separation models and can split vocals, backing vocals, drums, bass, guitar, and other stems from uploaded audio.

MusicLM is a Google Research audio generation model that creates music from text captions at 24 kHz. The public examples page hosts sample clips for prompts like arcade soundtracks, reggaeton-EDM fusions, and relaxing jazz, plus longer story-mode generations that shift styles across timed segments. Google released the MusicCaps dataset of 5,500 music-text pairs alongside the paper.

Unlike consumer apps that ship one prompt box, MusicLM was published as a research demo with pre-generated samples rather than a login product. Its headline trick is joint text-and-melody conditioning: you can hum or whistle a tune and have the model re-render it in a new genre described in text. Story mode chains multiple captions so the music evolves across sections.

MusicLM matters as the research foundation behind Google's later Lyria music models, but this page is for listening to published examples, not creating new tracks interactively. Researchers and musicians study it for long-form consistency, painting-to-music conditioning, and melody transfer results documented in the 2023 paper.
