In 2008, two years after graduating from BRIT School, a fresh-faced young singer called Adele released her debut album, 19. The album was a runaway hit thanks to her first major hit, "Chasing Pavements", an absolutely massive track that was inescapable for years after its release.

But before all of that, she released her debut single, "Hometown Glory", a tribute to her home suburb of West Norwood in London. The story goes that Adele wrote the song in a mere 10 minutes when she was just 16 years old.

Initially, the track didn't even chart, but when it was re-packaged and re-released as part of 19, online downloads sent the track surging up the charts. Before long, it was getting covered by Gabrielle Aplin, Shawn Mendes and more.

Its biggest impact, however, was in the UK rap scene. In 2011, a flurry of tracks and freestyles emerged, all built around a sample of the song's rousing piano melody. That year alone, it featured in releases from Sneakbo, Yungen and a Behind Barz session from Krept & Konan. Even stateside it got sampled by Big K.R.I.T, Lil B and Big Sean.

Had the track not found its second wind and a re-release from XL, the trajectory of UK rap might have looked entirely different.
