A heartfelt declaration of love arrives with “I Do,” the sixth track on Harmonize's newly released 31 album. The Tanzanian Bongo Flava star joins forces with Ya Levis, the Congolese French singer known for his smooth R&B and Afro-pop sound, creating a cross-regional collaboration built around romance and commitment.
Rather than chasing a club-focused direction, “I Do” leans into the emotional side of love. Harmonize expresses his devotion to a woman he considers his one and only, with the song gradually taking the shape of a promise to remain committed. The repeated “I do” sentiment gives the record the feeling of a personal vow, making marriage and lifelong companionship central to its message.
Ya Levis adds another layer to the record with his silky vocal delivery, complementing Harmonize's melodic style while bringing a Francophone/Central African influence into the predominantly Tanzanian soundscape. Their contrasting backgrounds make the collaboration feel naturally Pan-African without taking attention away from the song's romantic core.
At 2:59, the track maintains a relaxed 92 BPM groove, giving both singers enough room to deliver their melodies without rushing the emotion.
Coming after the solo “Huyu,” “I Do” expands the romantic thread running through the early portion of 31 while introducing one of the album's international collaborations. It is also the first official collaboration between Harmonize and Ya Levis, making their pairing one of the more distinctive moments on the 14-track project.
