Rename files when download playlists

[andycor]

Hi all,

I've using Subsonic in the last years, and from time to time, I use to download albums or playlists to my mp3 player, just to listen while traveling. Something that annoys me is the fact that the files are downloaded with its original name, and in the case of playlists, the order is completely lost.
It would be very useful when downloading playlists that the filenames can be renamed to "Track Number - Artist - Song Title" or something configurable, in order to allow keeping the original order of the playlist.

Thanks!
