Lacuna Coil, one of my favorite bands and god is Cristina Scabbia gorgeous!
Slipknot and Stone Sour, because Corey Taylor is awesome and I love how he sings differently for the two bands so they sound more unique and not just like one is a side project of the other with practically the same sound.
Symphonic Metal has been really starting to grow on me the last year or so and so many bands I enjoy to name them all...
