Usage: mp3tag [-a <artist>] [-s <songname>] [-l <album>] [-y <year>] [-e etcetera] [-g genre] [-k track] [-r] filename [..filename]
Flag -r merges new ID3-info with existing ID3-tag in file.
For a list of supported genres, use '-g list' (the genres are compatible with WinAmp)
Maximum lengths:
Artist : 30 characters
Songname : 30 characters
Album : 30 characters
Year : 4 characters
Comment : 30 characters
Genre : 1 integer [0..254]
Track : 1 integer [0..255]
If you don't specify any of the id3-tag fields, the file's id3tag will be shown only.
The TRACK option is only supported for mp3players that support the ID3V1.1 standard (other will probably just ignore it). This cuts off the length of the comment field to 28 characters if used.
