Girl group HEART OF WOMAN has officially released their mixtape 'H.O.W's Delight' as a digital single to mark their 100th day since debut. The track was made available on various online music sites starting at noon on the 4th.

■ Ryuin's Italian Rap... A Modern Reinterpretation of 2000s Hip-Hop

'H.O.W's Delight' is characterized by a sound sampling an Italian art song and member Ryuin's Italian-language rap, drawing fans' attention even before the group's debut. It is also the work that first introduced the group's presence through a video shot in Los Angeles, USA, and film footage capturing a sophisticated mood.

Musically, the song reinterprets the feel of 2000s hip-hop in a modern way using vintage strings and heavy drum grooves. Members Chaei, Riri, and Ryuin each participated in writing their own rap parts to express their individuality, with Ryuin's Italian rap in particular standing out. The repeated chorus and diverse flows carry HEART OF WOMAN's own free and confident energy.

The cover artwork reinterprets a scene of the members' bright smiles from the music video of the included track 'Dalla ($.$)' in a cell animation style, visualizing the song's joy and free-spirited atmosphere.
