On occasion, I listen to Wrock. It makes me realize that HP will never be over, and that there are some people out there who get it. Sigh.
A few top choices: Accio Love//Ministry of Magic; End of an Era//Oliver Boyd and the Remembralls; Open at the Close//Oliver Boyd and the Remembralls; The Boy Who Lived//Oliver Boyd and the Remembralls (pretty much anything by him, actually, since the singer can actually sing); Amortentia//Let’s Lumos (feat. Oliver Boyd and the Remembralls); Harry Potter (Before We Say Goodbye) (technically this one isn’t Wrock, it’s just a parody of “Hey, Soul Sister,” but it’s SO catchy and wonderful); Like It’s Quidditch (again, a parody of “Like a G6,” but far, far better than the original song).
