Local tracks are unavailable, even though they are able to be played.

l tracks come up as unavailable(greyed out) on the same computer that they are present on. It means I can't even sync the song to my phone. It's fairly random which songs are unavailbe to spotify and changes with each start up.

Double clicking on them allows to be played, but because spotify thinks they are unavailable it never plays during shuffle play.

I noticed this happening a few months ago.
