Beats marketplace BeatStars signed a partnership deal with AI music startup Lemonaide that will make “ethically-sourced AI” available to music creators to help them write and produce new works. Lemonaide’s AI technology “purposefully generates short musical ideas to spark inspiration, push creative boundaries, and pull artists out of their creative slump,” according to a press release. The companies claim the AI is “trained exclusively on voluntarily contributed data from producers” to ensure proper compensation for and active participation by those whose musical works are used.
