As someone who’s spent quite some money on Focus@Will, I was excited to get an invite to Google MusicLM (under the “AI Test Kitchen” umbrella). Unfortunately, it’s so bad:

• prompts take little effect, it’s more like a random generator. Could not even reproduce the example from the abstract of the paper.
• very poor audio quality, like on a 90ies phone call
• very short, 20s pieces are long. No infinite loop.
• no iterative collaboration with the AI on the result
• no history - close the browser, results gone
• no download offered (not that you would want that trash, but…)

Focus@Will are under no threat as of now 🙂
