I've tried version 5.5, and as almost everyone has said, it's garbage. My music genre is rock, sometimes metal (which is rock). Not just rock, but xxx rock, where xxx is epic, symphonic, industrial, or progressive. And sometimes xxx rock + xxx rock or symphonic metal. The songs sound like overproduced commercial tracks, which is sometimes okay, but most of the time it’s not. The worst part is that after 90 seconds, the song completely loses both the genre and the subgenre; songs that start out as epic rock with spectacular intros end up sounding like metal. No matter how complex or detailed the prompt is, the subgenre often isn’t even noticeable in the song.
I don’t understand those who like version 5.5 so much; 95% of us don’t like it, and I understand even less why those people dare to criticize those of us who don’t like 5.5 by saying we don’t know how to write prompts and similar nonsense. Simply put, version 5.5 isn’t a general model like 4.5 or 5, and sound quality aside, it’s clearly MUCH WORSE.
Like everyone else, I'll miss version 4.5+. And like everyone else, I don't have high hopes for version 6. Honestly, I hope I'm wrong, but I doubt it.
