TagFormat is not working properly

[ischowam]

I now tested it a bit one by one and come to the following conclusion/summary:

I created 3 testfiles per folder and used these tags:
- artist
- album
- track title
- track no
- year

Only in these cases Bubble UPnP shows the customed tag with "album [year]" (some blanks are removed in this post):

1: within the 3 files there appear more than one album-name (Test-2)
2: within the 3 files there appears a track-no twice (Test-4)

I attached a TXT-file showing the tags.

I also could provide a ZIP-File with my testfiles (only silence in it) including a folder-tree, but it is too large for being attached (5,4 MB)
