What are MP3 tags?

MP3 tags, also known as ID3 tags, are metadata containers embedded within MP3 audio files. They store information about the audio content such as song title, artist name, album, year of release, genre, and even album artwork. These tags help music players organize and display your music collection properly. Without tags, audio files would just appear as generic filenames, making it difficult to manage large music libraries.
