Rhapsody's sound isn't like Dragonforce's. Dragonforce has like 5 minute shred sections, no symphony/barely any keys at all, blast beats, more old-schoolish riffs. Rhapsody has a 6-album-and-counting fantasy storyline, while DF just has standard vaguely-fantasy power metal lyrics. Those are just a few examples, but I don't think they sound alike at all.
