ID3
From Just Solve the File Format Problem
ID3, or ID3 tag, is a metadata format, used mainly in MP3 audio files. It stores information such as the song title, artist, and album.

Format details
There are two major versions. ID3v1 defines a fixed-length data block that is always placed at the end of the file. ID3v2, which has very little in common with ID3v1, defines a block with variable-length frames and allows more flexibility and verbosity.
Identification
An MP3 file with an ID3v2 tag begins with ASCII "ID3".
For an MP3 file with an ID3v1 tag, ASCII "TAG" appears beginning 128 bytes from the end of the file.
