I'd like to completely replace my PC (J River Media Center) and Android (PowerAmp) music players with Plex. It would be great if Plex supported ReplayGain for gain control (levels out volume levels across songs or albums by reading ReplayGain ID3 tag data).
Replaygain is a feature existing already in the Audio Engine of XBMC Frodo. Even though the feature might not be accessible through the preference panels of PHT there is a fair chance that it can be manually activated and set by adding an advancedsettings.xml file.
