I\'d love to be friends! Nightwish and Epica are VERY similar to Within Temptation. So you would probably like them! Nightwish is my FAVORITE band, they are the BEST band I have ever heard. All the members have been classically trained and the lead singer was classically trained as an opera singer! She is a professional opera singer! I\'m glad you liked the song! ^_^ I LOVE IT!! Here is a link to a song called Memory (from Cats) done by Epica: http://youtube.com/watch?v=-pu4eqMQp1I Here is a link for a song called Bless the Child by Nightwish: http://youtube.com/watch?v=LaNQWWlyS3g And another clip of Nighwish, a song called Nemo which is probably their most famous song: http://youtube.com/watch?v=4mis93XSbzU
