What does matching my library do exactly?
Rdio's Mac or Windows apps will first find the file on your computer that describes what is in your iTunes or Windows Media Player library. It then reads the file and looks for names of artists, albums and songs and sends those names to Rdio. The artists, albums or songs you have in your library that Rdio also has in its catalog, will be added to your Rdio Collection. It’s a quick and easy way to match the collection you have on Rdio with the one you have on your computer, so you don't have to start from scratch.
Does that mean I’m sending you all my MP3s?
No. No song files are ever sent or uploaded or in any way transferred from your computer to Rdio. It’s simply a list of artists, albums and songs that is sent.
Does that list stay linked to me?
Nope. We do the matching, and then disassociate the list from your account. You can sync your library as often as you like and only new artists, albums and songs are added to your collection on Rdio.
How do I match my collection?
From the File menu, select Match Collection to match tracks from your existing iTunes or Windows Media Player library with Rdio’s catalog.
Match Collection reads your (music) library file, looks for names of artists, albums and songs, and sends those names to Rdio. Tracks that it finds will be added directly to your Rdio Collection.
What if my iTunes library is in a custom location?
Rdio for Mac will automatically search for your music library file in its default location: /Users/[your username]/Music/iTunes/iTunes Music Library.xml
If your collection of music is somewhere else (say, an external hard drive), you can click “Change” to manually specify a different location.
Why do I see songs or albums on Rdio that weren’t matched?
Collection matching is an imperfect science, and unfortunately variances in metadata can make it so that some available artists/albums/songs aren't matched.
Match Collection didn't work at all for me! What should I do?
- Make sure you're using the latest version of iTunes.
- On a Mac, make sure your Applications folder permissions are set to read/write.
