Actually, it seems to go a bit beyond that. My .m3u playlists that I imported to my HTC One using Double Twist always have a lower track count than in iTunes (or other player on Android). After some tests it turned out that no entries containing German umlauts (äöü) are recognized. They are just ignored by Poweramp. It would be great to have an update for this. If required, I can send one of my .m3u files. To be honest, I haven't tried to create new playlists with Poweramp because it wouldn't be much fun to rebuild a 1000+ song playlist - especially when all other players I have tested have no issue with this. Besides this issue I love Poweramp! Thanks for making it!
