There just seems to be no proper solution to this topic... I to today have found only to applications for PC/mac. MusicBrainz Picard, which in the last month has become somewhat unresposive... and then the TuneUp addin for itunes or media player, which is regardless of the very large base it has behind it very inaccurate... Even though i searched a lot of this topic i did not even catch what are all the solutions and databases that are avaible for that in the world... Because soundhound/shazam are both getting different resulst... For now i recommend Picard for automatic tagging, or soundhound for manual :> If that would be implemented in any player and it would get really god results that would really be it. BIG TIME. but as far as i learned the databases are payable.
