Hip-hop and R&B offer some of the most fluid, dynamic sounds today, true barometers for where the culture is at and where it’s going. This week, headlining #OnRepeat—a playlist chock-full of the hottest new songs we can’t seem to stop playing—is Chicago MC Chuckyy’s “My World.” The song is anchored by a sample of Vancouver-hailing singer-songwriter EKKSTACY’s “I Walk This Earth All by Myself,” Chuckyy borrowing the original’s conspicuously emo tone. The Chuckyy spice is less self-pity than personal affirmation, the MC telling us, “I walk the world by myself ’cause I did this shit all alone.” Listen to “My World” on the #OnRepeat playlist, and if you hear something you like, add it to your library.
