Would Any One Care To List Me Some Band NamesThat Are Good To Listen To?

I feel I'm deprived of some music and would like to listen to some other bands since I keep over hearing the one in my ipod. Care to give me some names that I could listen to? :]

Here’s the list of bands I already have:

Nightwish
Flyleaf, Paramore
My Chemical Romance
Drowning pool
Blood Simple
All That Remains
Nickel Back
Fall Out Boy
Within Temptataion
Techno -it’s not a band, just techno music.
Evanescence
30 Seconds To Mars
Emilie Autumn
Red Jumpsuit Apparatus
The Used
Underoath
LifeHouse
MSI
Green Day
Blue October
Linkin Park
Three Days Grace
Dir En Grey
Metallica

-Takes a deep breath- Well..that’s pretty much all of it. If you could add on that would appreciated X]

The types of music I like are Techno/rock or classic/punk/and metal
