How can I automatically correct tags of music files? I've seen apps like Shazaam and TrackID, which can provide the Artist, Album etc. info, by recording a few seconds of a song from any source.
In my music gallery, there're lots of songs, with incorrect artist, albums or genre names. So is there a way that allows me to automatically correct these info, or at least fill up the missing info?
If you can use the Sony walkman app, that is the best solution for you. See the answer in this question. If that app is not compatible with your device, Album Art Grabber would be a good solution for you.
