@pauljam, haha thank you! Ok let's see.

The bands you recommend me(Gloryhammer,Lost Horizon) i'll check them out. I like Alestorm from time to time, so the it must be good.
The other sugestions, Blind Guardian, i'm not a big fan, but i've heard before a few albums, it's good(because reminds me TLOR) but i prefer Rhapsody of Fire. Metalium & Falconer, well i don't like those
But the other sugestions i'll listen to them! Thank you.

@Blade_PT, i've heard Sonata, not a big big fan but i like it. Symphony X is a must if somebody listen Dream Theater, so yes i've already heard them, good albums!.
About Circus Maximus... i've always heard about them but i haven't listen any song yet; so i'll take it. ! Thank you!

If you guys have some other bands in mind with good melodic voices, just let me know. Thanks!
