...or when you set your search to 'entire library'.
And so to the original question:
The icons are shown here following a search and identify the location of the track:
The folder plus note is shown when the track is found in the inbox.
The play icon (?) is shown when the track is found in audiobooks.
The musical note is shown when the track is found in the music library.
(The icons are specific to the skin used).
Presumably you have two copies of 'Wishin' and Hopin'' - one in your Music library and one in the Inbox.
