Keep ID3 tags to organize music library
ID3 is a metadata container most often used in conjunction with the MP3 audio file format. It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself.
After the conversion, with ID3 tags kept, users won't mess the large amount of music files around, because while converting Spotify audio tracks, users will get almost all ID3 tags including title, artwork, artist, track number for organizing your music library.
