"This song is unavailable" after adding local file then removing it.

[markFreedom]

Repro:

• Add a song that is available to play from Spotify (not local)
• Add a local source that contains a file whose track information matches the not local track information
• Remove the local source
• Go back to the song that you added in Spotify and attempt to play it
• Note that an error will occur: "This song is not available"

You can even try removing the track from your playlist, finding it on Spotify, and re-adding it - it will still not play.

Please help! Most of the music I like I had locally and it is hitting this issue.
