Music: Kings of Leon and Muse(just seems like the kinda bands that will enter in that status classic rock, I was gonna say Radiohead but pretty sure they're older songs I already considered that) also Jay Z (his old 90s raps are already classics blue print 3 will become a classic), Beyonce music (next Diana Ross imo)

Movies: Inception, Princess and the Frog, Ratouille however you spell it, Toy Story 3 (will definitely be Disney/Pixar classics), Inglorious Basterds, Avatar (unfortunately), Harry Potter Deathly Hallows (the rest of the movies too), The Hangover, Black Swan, The Dark Knight, V for Vendetta
