Tiny detail question - I thought the $IsNull might do this, but looks like it doesn't (for me).
Can this be configured to only 'fill' / show the custom link in the Track Information panel IF there is a given ID, so it resolves to a legal/real/functional html URL (there's still a few tracks that do not have the discogs ID, in that case I would prefer if the custom discogs links wouldn't be shown in Track Information panel... if that is possible...).
Churs.
