seems dBpoweramp writes the reply gain as expression -9.73 dB, jriver wont read the 'dB', but jriver it read the flac and wave dB. i can't change how dBpoweramp writes this.
how about Disc #?
scrap that, jriver ape replaygain tag reader seems broken. i tried without dB, but still not working i guess it was reading from library when jriver wrote the tag, and not from file tag by dBpoweramp. i prefer not to convert 50,000 files to ape and have JRiver redoing reply gain analysing when the tags are already available, will take a long time to reanalyse. i really hope this gets fixed... please
