I think in typical usage cover images for standalone recordings will be
embedded and different for each file. It's more like a list of 1-track
albums rather than a list of tracks from the same album, so probably
nice to add the images.
$menu //= "MenuMPDRecordings";
my @tracks = sort { $a->{Title} cmp $b->{Title} }
grep { $_->{Album} eq $albumname } @recs;
+
+ # Show thumbnails for standalone recordings
+ my @thumbs = get_item_thumbnails({ small => 1 },
+ map { $_->{file} } @tracks);
+ foreach my $entry (@tracks) {
+ $entry->{thumb} = shift @thumbs;
+ }
+
my @notqueued = update_entry_ids(@tracks);
fvwm_cmd("AddToMenu", $menu);
