🗒️ Introduction to Id3

Wikipedia article ( for tag info ) : https://en.wikipedia.org/wiki/ID3

There are different version of Id3 such as ID3v1, ID3v2 ( v22,v23,v24 ). Id3v1 is too old school and there isn't much in that. So, this extension converts/copies your old ID3v1 tags to ID3v24 if it's the older version so that it ensures that you can use all the tags in your audio file.
