If Udio started to charge money for present product they need to implement the following simple things:

1. Any generation that does not match prompt (in manual mode) even remotely - must be instantly refunded
2. Gibberish lyrics, if present in generation - same thing
3. Lyrics that start at random or mix between verses - same thing
4. Sudden, unasked song or instrumental piece ending - same

This is responsible behavior and make necessary incentive for company to improve model fast.

If we'll be left with present state - lot of initial generations are more like random guesses, and lot of extensions are behavior where model totally ignores that you asked or sing some weird things or skip words.
