That song is utterly mediocre except for the guitar solo (the only mildly enjoyable part), whiny vocals with boringly flat lackluster riffs and nothing else thrown in to make it more interesting or complex either. This is exactly why typical old-school Power Metal doesn't do much for me, and exactly why Symphonic Power Metal, with the addition of keyboards, choirs, more guitar solos, use of elements from classical music, etc is SO much more superior to it. Needless to say, the Keldian song that you mentioned "Requiem For The Light" is infinitely superior in every way to that old clunker of a song that you just posted.
