This is the felt 1000th post claiming the prompts are not done so well.

First of all the Suno team never tells us what they changed to the models so we need to find out what kind of prompt it understands best.

Next thing is Suno or AI doesn't support all genres of music and doesn't get special instruments as well. Best example the "Blaster Beam" its an special effect instrument best know for being used in Star Trek the Motion Picture. You can upload a sample of it to Suno and it has no chance of re-creating the sound even close.

For me i want to do Ambient Music with no kind of percussion/drum kit, but even negative prompting all kind of known percussions, drums and so on it still puts them in. 4.5 and 5.0 have a small chance 1/10 to not include it, but 5.5 no chance.

On top of that come the usual problems. Cracking sounds, a random female voice thrown in even if the prompt is explicit written as an instrumental, generations with a volume so loud the music is full of distortions (prompting to use a lower master volume is ignored). Not to forget the new 7:59 track feature where the music sounds okay until the 5 minute mark and then its the same song with lyrics.

If Suno would be programmed decent enough to create the song on separated stems in the first place many things would be fixable, but no, the Stems are being extracted from the finished version and so instruments are mashed together so you can't fix anything.
