Consider that Luka has onver 3,000 songs at least and you'll see the problem with listing songs. It would take a few days to find them all, check if they were English or Japanese and write down all the names. Most are Japanese, the most common use of English vocals is random english inserts into songs. Therefore, we cannot comply a list of English songs, they do exist such as Circus Monster, Secret, etc, but their harder to find.
It gets worst if you go over to listing anything related to Miku, she has over 100,000+ songs.
