Amazing song quality with HeartMuLa

HeartMuLa has the best quality of all song generation apps I've tried so far.
This is more than you'd expected from an application that can run locally on your computer.
Its strength lies in emotional, dreamy, moody, romantic rock and pop music. But not exclusively.
It might still have some problems to follow certain prompts. But it's just at the beginning.
The app consumes about 21GB of VRAM. On an RTX 5080 (16GB VRAM) a song needs about 550 - 700sec to generate.
The waiting time is worth it. Even if the songs don't always match the prompts, the outcome will often blow your mind.
Tags for verse and chorus for your lyrics work but aren't necessary. The model can distinguish the parts.
Simply write your style prompts comma separated without spaces.
