Wait, JIA (pronounced Jee-ah) is an R&B artist known for her blend of pop and soul. She has released several singles and EPs. If "Deeper" is an EP or album, Part 5 might be the fifth track. Let me confirm by searching her discography. Yes, she released an EP called "Deeper" in 2023. Part 5 would likely refer to the fifth track on that EP. The date 05102023 aligns with the release date. "Extra Quality" might be a bonus track or an extended version.
