Extended MP3 Tag is free. It enables you to manage your MP3 files on your smartphone fast and easy. Tagging your music library allows you to sort music by genre or year but it also saves album covers correctly what makes identification of the played song very easy. Old CD titles or music bought on other devices or stores are very suitable. Also music from SoundCloud is often untagged and as long as songs were published in iTunes it is so fast and easy to tag them.

The following tags can be edited: Title Artist (Lead Performer) Albumartist (Band) Album Year Genre Titlenumber Total number of Titles in the Album.

Very helpful is the iTunes search because it makes it way more easy to tag. Therefore just select a music file and press the search button on the top right side. Type the search term into the input and press search in the keyboard.
