Comment 1 for bug 618182

the problem is not only with roman numerals
lyrics.wikia needs camel cased titles, thats why case convertion is required, this transforms IIV in Iiiv, but lyrics.wikia uses a case sensitive search , so the search fails with roman numerals, but also with song names like SPORT (an acronym)
I've made another plugin, lyricswikia2, it downloads all artist song title from lyrics.wikia and uses its own case insensitive search, but may be a little bit slower when downloading song list for the first time
