Use scanf-like and regular expressions pattern-matching to disassemble groups of song names and reassign text to correct tags. For example, parse the song name XTC - English Settlement - 15 - Snowman using the pattern %a - %l - %t - %n, sending artist, album, and track number to their appropriate tags. Read Me is quite clear and helpful.
