Hi, I'm just about to normalize my music library for Poweramp app on my android. I tryied it with Mp3tag on PC. But, for instance, the changed genres didn't appear in the app. Could it be a problem with the supported mp3 tag version? Wich one should I choose? Which should be deleted? In Mp3tag I can choose ID3v1 / ID3v2.3 UTF-16 / ID3v2.3 ISO-8859-1 / ID3v2.3 UTF-8 / ID2v2.4 or APE. Thanks in advance for your ideas.
