Mixxx 1.12 alfa can read the libraries of Rhythmbox, Banshee, iTunes, and Traktor.
Could support for the Quod Libet (QL) [1] library be added to Mixxx?
Even without Mixxx integration it is already possible to do the following:
* drag and drop a song from QL into the Mixxx main deck, sampler deck, preview deck.
* drag and drop a playlist or song from QL into a Mixxx playlist or Auto DJ pane, and the songs will be inserted under the position defined by the cursor.
The QL “database” (so to speak) consists of:
* a list of songs which is a a pickled list of AudioFile instances [2] stored under Linux at ~/.quodlibet/songs.
* a folder in which playlists are stored, which under Linux is at ~/.quodlibet/playlists. Each playlist is a plain text file with the full paths plus file names of the songs.

We already have a file based library import for iTunes. So it should be relative easy to adopt that to Quod Libet.
Feel free to create a GitHub pull request for it.
Do you need help? Just ask.
