i threw $10 into it to play with the new V3 algorithm much like dall-e it's wildly impressive at first glance and the more you bang your head against it, the more the cracks show it's very repetitive, doesn't often fit lyrics properly into bars, song structure often makes very little sense, the list goes on it is simultaneously very cool and incapable of accomplishing its goal reliably.
Like with good art, you need to learn how to appreciate it, see it not for whether it can be useful to you for 10$, but for what it can be in the future with a cost structure so cheap they can afford to run it on 10$ subscriptions.
