My music collection is on a separate partition and not under
/home/username/Music. How do I get the music lens in Unity on Ubuntu 11.10 to search in a different location?
It shows what is inside Banshee's database so you could update this. How to register downloaded podcast mp3 in Banshee? probably answers how to do that.
You can also
symlink your music directory. That way anything thinking it should look in
~/Music/ will look in your folder.
You can do that like this:
cd /home/username/ mv /home/username/Music /home/username/Music.old ln -s /your/path/to/music/ Music
You can just remove
Music.old if you don't need it.
I assume that rescanning the folder would add them to your database.
