ID3tag
The MP3 file format, didn't provide any means for including metadata about the song. ID3 tags were invented to solve this problem.
You can tell if an MP3 file includes ID3 tags by examining the last 128 bytes of the file. If they begin with the characters TAG, you have found an ID3 tag. The format of the tag is as follows:
TAG song artist album year comment genre
