Music supervisor for indie films here. We've started using Udio for temp tracks and some final background music. Important legal reality check: while Udio gives you a license to use the outputs, the copyright status of AI-generated music is still unsettled.
The US Copyright Office hasn't definitively ruled on AI music. If someone copies your Udio track, your ability to sue for copyright infringement is unclear. The license from Udio gives you permission to use it — it doesn't give you copyright ownership in the traditional sense.
For background music in podcasts/video, this is fine. For music you plan to distribute as standalone songs and want to protect, the legal landscape is still murky.
