Off the top of my head, I'm not sure there is going to be an automated way to do this, unless you've left your iTunes music folder intact, and are pointing Subsonic to it. If that's the case, you should be able to export a playlist from iTunes as an M3U, and import it into Subsonic.
If your music is in a different location, you could still use the exported M3U, but you'll need to change the file path. Here's an example of an M3U I exported out of iTunes:
- Code: Select all
#EXTM3U
/Volumes/SSD/me/Music/iTunes/iTunes Media/Music/Cannonball Adderley/Know What I Mean_ (with Bill Evans) [Bonus Track Version]/05 Toy.mp3
#EXTINF:262,In the Still of the Night - Sonny Criss
/Volumes/SSD/me/Music/iTunes/iTunes Media/Music/Sonny Criss/The Complete Imperial Sessions (Bonus Track Version)/07 In the Still of the Night.mp3
#EXTINF:446,Minor Mishap - Kenny Burrell
/Volumes/SSD/me/Music/iTunes/iTunes Media/Music/Kenny Burrell/Tommy's Tune/08 Minor Mishap.mp3
So, using a text editor, you'd need to replace each path (e.g. /Volumes/SSD/me/Music/iTunes/iTunes Media/Music/Cannonball Adderley/) with the path to where the music now resides, assuming you haven't changed the names of the files themselves. A simple regex would do this in short order.
One note: Subsonic does not do smart playlists--feature request, please!--so any such playlists will obviously become static.
