I guess Poweramp is the only Android player that supports ReplayGain. If this feature is activated it would be cool to see the applied RG value in the meta info below the seek bar. PS: RG tags in mp3 are not standardized. Which ones are supported by Poweramp? The ones made by mp3gain (in an APE tag) or the ones created by foobar2000 (in a special id3v2 tag)?
