I have my mp3 collection on an external hard drive. Some of these files are included in my offline playlists - those I listen most often.
However, if the hard drive isn't connected, Spotify still tries to access those mp3s from the drive, not from the offline cache, thus making those particular songs unavailable to me unless the hard drive is connected.
I found a workaround for this, by having two mp3 libraries - keeping the most important files in a local folder and the rest on the external drive, but this isn't very convenient...
So the question: Is there a way to make Spotify cache those mp3s for offline access?
