EvilLyrics can't parse special characters (apostrophe, ampersand, etc) and stops right there at the first instance of special character replacing it with underscore (_).
Example:
Song1: Alicia Keys - Fallin'.mp3
Song2: Alicia Keys - Fallin' (Remix).mp3
Lyric (for both songs): Alicia Keys - Fallin_.txt
Those two songs have different lyrics but ended with just one.
actually no.
it replaces non standard characters with underscore (in this case a apostrophe) and removes everything in brackets. option to not ignore bracketed text will be included in the next version
