Old Internet Radio

[zfc]

As a workaround I have introduced a custom tag "BestQuality" and given BestQuality="Best" to all files except those mp3-files where also a flac-file is present (BestQuality tag not given to the rest). I have set indexTag to "#AudioFormat:FileFormat, BestQuality, ...". Selecting FileFormat->MP3 on the old InetRadio and BestQuality->Best on all other players results in the correct subset of files but is less elegant than I had hoped for. It would get a bit better if at least I could combine #AudioFormat and BestQuality into one Index, but with valueTag "...merge={#AudioFormat, BestQuality}..." I get an error message and so I do when aliasing #AudioFormat:AudioF in indexTags or itemTags and putting "...merge={AudioF, BestQuality}...". Is there a way to combine #AudioFormat and my BestQuality tag into one field?
