I meant to get back to this thread earlier. The last creations I had on Udio were from eight months ago. After you mentioned your issue, I tried creating four tracks, and one of them had the goofy error your had, and one other just came out as complete jibberish – the “Simish” you mentioned. That’s weird, as I have about a hundred songs in my library, and not a single one has “Simish,” though a few have words inserted or changed. It seems like the current model is buggier than the old one. Huh. Will have to check out Suno soon.
ETA: Just checked out Suno and, yeah, it seems to be much better than Udio now.
