12. 'Wild Style' (1983)
Wild Style was a breakthrough back in the day, when there were barely any actual hip-hop albums, let alone soundtracks. The 1983 film, about an ambitious young graffiti writer, was an early look at B-boy culture, showing DJs and MCs at work – Grand Wizard Theodore, Busy Bee Starski, Rammellzee and more. In the big scene, the Cold Crush Brothers have a rap battle with the Fantastic Freaks on the basketball court. None of the songs were hits, but it's an essential old-school document.
