Display Replaygain Album Tags – anomalies

[PhilE]

Following Forum member Timster, I added replaygain_album_gain to itemTags and Album.displayFormat={$album^$replaygain_album_gain^ (^)} to tagFormat.

For the most part the results were as expected – one RG value in brackets after the album name and two RG values if it was a 2-disc album.

But there were quite a lot of single disc albums where either no RG value was shown or where one or more RG values were displayed.

I looked at the tags on a single disc album that had 2 RG values showing. On one track the RG album value was different to all other tracks as the RG album value was the same as its RG track value. I used DBpoweramp ID tag converter and this resulted in all tracks having the same value for RG album. However, after re-scanning the same 2 RG values were still being displayed as before. I looked at the tags again and saw it had an ITUNNORM tag. I deleted this and now after re-scanning it displays a single RG album tag.

Next, I looked at the tags on a single-disc album that had 3 RG values showing. This had 3 works (groups) and each one had its own RG album value. (I have many other albums that use the group tag and for these only one RG album value is being displayed). I again used DBpoweramp ID tag converter and this resulted in all tracks having the same value for RG album. However, after re-scanning 4 RG values were now being displayed – the 3 it had previously plus the value applied by ID tag converter. Again, I noticed that there was an ITUNNORM tag but when I deleted this and re-scanned 4 RG values were still being displayed.

I then turned to some single disc albums where no RG album value was displayed. I looked at the tags for 2 albums: both had RG track values, but no RG album values; and neither had ITUNNORM tags. I used DBpoweramp ID tag converter on each album to add the RG album values. But after rescanning no RG album value was displayed. I then used DBpoweramp ID tag converter on a batch of 3 albums by the same artist. These also only had RG track values and no ITUNNORM tags. With the RG album values added to the three albums and after rescanning the RG album value was displayed for one of three but the other two still had no value displayed.

I’ve checked Log in Minimwatch and there are no errors listed.

Could someone please advise me on how to deal with these anomalies.
