I don't know if this is a regular complaint against Sonata Arctica, and I'm not saying this to get a reaction, and I respect that people like them, but...
They just seem very cheesy. The music's great, but the vocals and lyrics just put me off a bit because they seem cheesy almost to the point of parody. Again, I apologise if this is said a lot, and I'm not saying they suck or anything.
