Add Rapgenius Parser to lLyrics 

Rapgenius.com is one of big database of lyrics for Rap Songs mostly, So I've just added a RapgeniusParser to lLyrics.
there's a utf-8 character in (line 58) that i think broke Parser. it doesn't break anything else in lLyrics or throw any error to debug, but send "No lyrics found" to output When I run RapgeniusParser manually and it worked without any problem.
