Power metal :) I'll put the albums that I recommend in the brackets for you!
If you're not into heavier screaming stuff, then this is a pretty good subgenre for you. Go with Sonata Arctica (Ecliptica or the Last Amazing Grays), Powerwolf (Blessed & Posessed), Dragonforce (Inhuman Rampage), maybe Avantasia (The Wicked Symphony).
Interesting music could be more like pirate metal? Try Alestorm (Black Sails at Midnight and Sunset on the Golden Age) and Lagerstein (Drink 'Til We Die).
Edguy kinda reminds me of classic rock as well as metal, so they're pretty nice (Rocket Ride and The Joker). If you want some kind of funny music, try Steel Panther (and try not to get offended, they're a parody band :P I recommend the All You Can Eat and Feel the Steel albums.)
