Welcome to UK Rap List, where elite MCs represent the essence of UK rap culture. Heading up this week’s lineup is K-Trap with “Whistle”—a melodic drill anthem laced with an otherworldly streak. “I’m getting in my artist bag, trying new things and merging the elements together,” he tells Apple Music about the track co-produced by Young Chencs, Dirty Dave and Danesblood. “I feel like this is a happy song, it definitely makes you feel that way. It has a commercial sound to it but it’s still me, it’s still Trap.” The South Londoner has been one of British rap’s most recognised hitmakers for so long (since 2017 breakthrough hit “Paper Plans”), it’s easy to forget he first released music while hidden under a balaclava for almost two years. On second album SMILE?, Trapo reveals even more of himself on a stylish, 19-track trip of self-discovery and growth with bright guest spots from Blade Brown, D-Block Europe and Angel. Hear ”Whistle” on UK Rap List now, plus more fresh tracks from Central Cee, Little Simz and Headie One. We regularly update this playlist, so if you hear something you like, add it to your library.
