YouTube has signed a deal with music licensing store RumbleFish allowing YouTube users to buy copyright-protected tracks to add to their videos.
Called Friendly Music, the service launches next week, offering tracks from RumbleFish's existing catalog.
The music comes in the form of a downloadable MP3, is licensed for use indefinitely and costs just $1.99 per song.
There's a strict 'no-profit' caveat - if the user wants to make money from a video, it'll mean upgrading to a commercial license.
YouTube is keen to stay on the right side of litigious copyright holders. Videos using unlicensed music on the site are deleted, muted, or covered up with ads - which means the launch may go some way to eliminating the awful home-made music which adorns far too many videos.
"Friendly Music has thousands of songs in every genre from artists and labels around the world," say the companies. "And we add more music every day. It's just a dollar ninety-nine a song, and your video won't get blocked or muted."
While the catalog isn't packed with big names, there are still around 35,000 tracks to choose from. Artists include Justice of the Unicorns, Down By Law, Kool Keith and Cex.
The service adds to AudioSwap, which gives users access to royalty-free tracks, including some from RumbleFish.
There's been persistent speculation that Google is planning a full-blown music download service. An online store is expected sometime later this year, to be followed by a subscription service.
