Hi,
You should update to latest 4.1.15 (4.1.15.1830) and problem should be solved. If not please open support ticket from links above so tahtw e can go into more details and better handle that issue reports.

[Edit: Rusty] Can you confirm whether the problem is fixed for you? Thanks.

When displaying tracks in a playlist in artwork view, some tracks display unknown album and artist when hovering over them. When right clicking and selecting properties, there is no information displayed for these tracks and when double clicking to play them, sometimes the track plays and other times a different track in the playlist plays. However, when switching to Show Details, view, the correct information displays in the properties for the track and the track always plays when double-clicking it.
