Hi,
I'm currently developing such an app for videos, but using Tracker (the
gnome
counterpart of KDE-Nepomuk). I found that the best datasource I could use
is
actually DBPedia (LMDB misses quite a few titles). But for music, I think
MusicBrainz is the way to go. The source isn't published yet, but it'll be
soon, just the time for me to polish a few things.

Cheers
