I absolutely LOVE Hollywood Undead (: Everywhere I Go is my favourite, me and my friend always have contests to see who can keep going without mucking up the lyrics first - although it's hard for me since I don't swear haha. I saw them supporting Blackout, and since I knew they were supporting I checked them out and fell in love with City, and I bought their album after the gig because they were so amaazing and now i'm addicted.
Even my dad knows the lyrics. I'll randomly hear him walk around humming Everyhere I Go :L
