The are definately significant improvements from the beginning till today but still a lot to do following correctly (simple) prompts. E, g. to put out a dominat instrument or rhythm is mostly unsufficient, Either the KI cannot work with their names or is driven into a complete alternative way. In my opinion it not flexible enough to create arrangements in other styles than todays popular music, singers etc. Maybe it learns to much of that stuff so it cannot "focus" on other than mainstream taste. For everyday video background creation I am mostly satisfied with one of the options. In creating real good quality songs and arrangements there are platforms ahead.
