Here's some more for all you metal lovers!
Hibria - "Stare at yourself"
Hibria - "A kingdom to share"
Both great songs with inspirational themes.
Gamma Ray - "Fight"
Very inspirational lyrics, but the music is what it's about and that rocks too!
Sinergy - "Beware the Heavens"
Alexi Laiho from Children of Bodom on guitar!
Pyramaze - "Ancient Words Within"
Part of a concept album about the struggle of good vs evil, very well done.
Blind Guardian - "Otherland"
Blind Guardian's a must for powermetal fans.
Another worth checking out is "Fire dance" by Balance of Power. Same vocalist as Pyramaze, unfortunately I cannot find a link.
I find the powerful instrumentation along with light-hearted inspirational lyrics of powermetal very uplifting and empowering. It tends to avoid the common themes of death and hate a lot of newer metal features today. I suggest checking it out!
