Well for me it all started back sometime in 1997, one of my (then) online pals was raving to me about this band called Nightwish.
He ended up sending me the CD, I was blown away by the music, but the voice I was not so sure about, as I had never heard anything quite like it.
It was Oceanborn that really sold the band for me, I was in the Navy at the time, away at sea and listend to it 3 or 4 times a day, it got me through some rough times, so this is my Favourite Nightwish release to this day.
Wishmaster I like but is let down by lacking that certain X factor for me. CC is where Tarja's vox changes down a bit and the band added Marco and he certainly brings Nightwish back to life.
Once, is my second fave, pretty close to Oceanborn, almost the perfect album, that band sounding at it's peak, despite all the friction between Tarja/Marcello and the rest of the band.
DPP, I love, it took some getting used to hearing the music of Nightwish with a different singer.
Anette I love on the album, but the couple of times I have seen her live, she struggles sometimes and a couple of the old songs sound plain wrong with her voice.
Tarja, I love her voice, but her album, 'My Winter Storm', is a snooze for me, I still have never heard it all the way through.
I hope the next one is better.
