Probably a toss up between "Quest of the Manwhore" and "Dance of the Manwhore". xD
As for actual bands and the like...probably either "Gangnam Style" by Psy, "Hard Rock Hallelujah" by Lordi, or "Prodigal Daughter" by KillMatriarch at the moment. ^_^
...although "Bless the Child" by Nightwish is another favorite as well, it's hard to pick from so many great videos.
