Thoughts about music

Someone seemed very surprised when I told them I like Dragonforce. Why do I like them, though, when I dislike many other similar bands? Melodies. Dragonforce has a melodic sound, as opposed to a lot of heavy metal where they're loud simply for the sake of being loud. I dislike rap for the same reason: it lacks a distinct melody.

So, that said, can anyone recommend any groups similar to Dragonforce? That is, fast-paced, melodic, rock/metal like bands? :)
