Yeah, Nightwish can be an "acquired" taste. Hahaha
I've always had a somewhat strange taste in music...everything from Ernest Tubb to Metallica.
(About the only thing I don't like is rap.)
A lot of times, the more "unique" the sound...such as Nightwish...the better I like it.
Lately this has been not only my main "call-making" music, but also my exercise music.
(FYI/TMI...Hahaha...the band got a new singer in 2006, with a different sound, & so I admit to only listening to the pre-'06 songs.)
