Paid a woman for vocals on a track.I asked upfront if she could sing the assignment. She said yes.We negotiated terms and agreed on delivery in six days.Last night she messaged me. She delivered not one track, but two. Five days early.That was the first red flag. I only asked for one.I listened. Both tracks had full instrumental backing even though I asked for vocals only. Both were wildly divergent from the original song. The vocals had obvious artifacts. She delivered MP3s instead of WAVs.I ran AI detectors. Three said human. One said AI. I can’t prove AI was used, but I’m confident it was.Regardless, she failed the assignment.I considered disputing the order. However, I didn’t want the escalation overhead.So I won’t hire her again. Which is unfortunate, because if she had nailed this one job, I would have been a repeat customer.Total gong show. Worst contractor I’ve dealt with.
