Your favorite bands/artists.

Yes, you're right, there's no need to criticize Nightwish! The combination of metal and operatic vocals actually works well, and Tarja is amazing!
In my opinion, these are their most interesting songs:
Shi is my sin,
Wanderlust,
Dark chest,
Come cover me,
SleepWalker,
End of all hope

If anyone wants, I can provide the songs + lyrics; there seem to be a lot of fans here!
