Because he was nice with Tarja when Tuomas fired her.
But I prefere Tuomas ...HOT

this was a tough pick.
theyre all cool in their own ways.
Tuomas is the best keyboard guy ever whom has created the best melodies for every song.
Emppu is the best guitarist for nightwish his solos and unforgetfull riffs shall never be forgoten.
Marco is the best bassist and best male vocalist nightwish has ever seen along side Tarja and now Annette, he brought songs like "Wish i had an angel" and "Bye bye beautiful" to life.
Jukka is the greatest drummer ever seen in symphonic metal music his skill are just legedary.

Marco's Voice beat out Tuomas'keyboard skills. Though i would take them both anyday. =]

Respect the drummer. He's responsible for keeping the beat, which is really, really important.

Emppu is the best

Marco !

Tuomas is so overrated. Marco is awesome!
