The rapid rise of generative artificial intelligence (GAI) is reshaping the paradigms of artistic creation. In music, this transformation is particularly striking: new systems capable of composing, performing, and producing original works challenge traditional boundaries between author, instrument, and machine. Platforms such as SUNO and UDIO, capable of generating complete songs with vocals, instrumentation, and mixing from simple text prompts, represent an unprecedented technical and aesthetic revolution. This paper presents a research-creation project exploring the aesthetic and practical potentials of co-creation between humans and AI systems in recording studio settings. Based on ethnographic observation of music creators working with GAI tools, we analyze how AI transforms collaborative dynamics, creative processes, and the very notion of musical authorship. Our findings reveal that rather than replacing creators, AI acts primarily as an inspiration tool and collaborative catalyst, while exposing fundamental questions about creativity, agency, and artistic value in the age of algorithmic intelligence.
